[0002] The low-pressure cookers on the market are complicated to operate in terms of opening and closing. Some use the misaligned engagement between the lid and the pot body, which requires the cooperation of both hands to complete the opening and closing operation. Some are too complex in structure, making it difficult for users to understand their application. Some low-pressure cookers are prone to having the lid and pot in a half-open state during use, causing the pot and lid to not buckle, resulting in pressure leakage in the pot. Some low-pressure cookers also cause safety accidents when the fire is turned down due to inattention to excessive pressure in the pot during cooking. Summary of the invention

[0061] The pot cover 010 of this embodiment is a transparent glass cover, which is helpful for observing the cooking situation in the pot.

[0062] The normal operating pressure range of the micro-pressure cooker is between 1 and 2.5 kPa. The micro-pressure cooker of this embodiment realizes one-touch control and the lid can be opened at any time without turning off the fire. Overpressure can be naturally deflated, making it safer to use.

[0083] (3) Fix the decorative part in the mounting groove 0052 on the upper surface of the side ear body 013;

[0084] (4) Securely pass the fastening screw 014 through the fifth mounting hole 0181 in the side ear body 013 and tighten it to the ear seat 016 welded to the pot body 017.

[0085] The innovations of this embodiment are as follows:

[0086] 1) Rotate the knob cover on panel 005 left and right to open the cover: ( Fig.26 )、Close the lid( Fig. 27 )、Pressure regulation( Fig.28 ), to achieve one-key control function.

[0087] 2) Rotate the knob cover, and continue to rotate it when the cover is closed. The pressure adjustment guide groove 0044 set in the knob cover drives the exhaust push rod 020 to separate from the steel ball 007, and the steel ball 007 automatically blocks the first air hole 0231 of the first air valve lower part 023, thereby increasing the pressure in the pot. When the pot pressure reaches the set pressure value, the air valve visual rod 019 automatically rises from the fifth mounting hole 0181 of the air valve cap 018, and the air pressure in the pot is discharged from the second exhaust hole 0182 of the air valve cap 018. The air valve cap 018 is designed with large air hole exhaust and pressure visual exhaust, which reduces the problem of easy blockage during cooking and has an air pressure prompt function.

[0088] The working principle of this embodiment:

[0089] 1. (e.g. Fig.29) The fixing seat 001 of the cover is designed with a concave-convex groove 0013 inside. Two hand-feeling columns 002 installed in the knob cover 004 jump up and down under the elastic force of the tension spring 003, and the knob cover 004 has a vibration effect and makes a beeping sound.

[0090] 2. (such as Fig.30 ) The interior of the knob cover 004 is designed with two opening and closing cover guide grooves 0043 and a pressure adjustment guide groove 0044; one end of the exhaust push rod 020 is provided with a guide cylinder 0202; one end of the slider buckle 008 is provided with a toggle column 0081;

[0091] 1) Turn the knob cover 004 clockwise, and the exhaust push rod 020 stuck in the knob cover 004 moves to the edge of the pot cover 010 under the action of the pressure adjustment guide groove 0044; the exhaust push rod 020 pushes the steel ball 007 to separate from the first vent hole 0231 of the first valve lower part 023, so as to achieve rapid exhaust. At this time, continue to rotate the knob cover 004, and the toggle column 0081 on the slider buckle 008 stuck in the knob cover 004 drives the slider buckle 008 to open outward under the action of the opening and closing cover guide groove 0043, so that the pot cover 010 can be separated from the pot. Turn the knob cover 004 counterclockwise to realize the folding of the slider buckle 008, and when it continues to rotate, it will drive the exhaust push rod 020 to move to the center of the cover, so that the steel ball 007 automatically contacts the first vent hole 0231 of the first valve lower part 023 in a sealed manner, so as to achieve pressure increase in the pot.

[0092] 2) When cooking, turn the knob cover 004 counterclockwise to close the slider buckle 008 and block the first air hole 0231 of the first air valve lower part 023 to increase the pressure. When the pressure in the pot reaches the set pressure value of 1-2.5 kPa, the air valve visual rod 019 automatically rises to warn that there is pressure in the pot and discharge the excess air pressure in the pot from the second air vent 0182 of the air valve cap 018. And keep the pressure in the pot stable within the set pressure value. When the pressure in the pot is greater than the unexpected set value (3-4 kPa), the air pressure in the protection device will lift the steel ball 007 and discharge from the gap between the steel ball 007 and the first air hole 0231 of the first air valve lower part 023. If the unexpected air pressure continues to rise to 4.5-6 kPa, the slider buckle 008 will be deformed, causing the pot mouth sealing ring 011 on the pot cover 010 to flip over and quickly exhaust air, thus preventing accidents.

[0093] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not deviate from the present invention should be included in the patent scope of this case.
