Description

Technical Field

[0001] This utility model relates to the field of pot lid technology, and more specifically, to a lid bead with manual venting function and a micro-pressure pot lid. Background Technology

[0002] Pressure cookers can be categorized into pressure cookers, pressure frying pans, etc. The pressure inside a pressure cooker is generally below 1.2 atmospheres. At this pressure, food is cooked more easily than in a regular pot, and the lid can be opened at any time during operation. To ensure both easy opening of the lid and maintenance of pressure inside the pot, pressure cookers either have a pressure-applying device between the lid and the pot body (but this makes the lid difficult to open and can easily turn into a pressure cooker), or they use a simple connecting device between the pot body and lid. In this case, the pressure inside the pot is difficult to increase, failing to achieve the performance characteristics of a pressure cooker.

[0003] CN211795876U discloses a micro-pressure cooker lid, including a lid body and a locking mechanism. The locking mechanism includes a first locking member and a second locking member symmetrically arranged. The first locking member includes a first translational part extending from the middle of the lid body to the edge, a first locking part extending downward from the outer end of the first translational part, and a first transmission part located at the inner end of the first translational part. The second locking member includes a second translational part, a second locking part, and a second transmission part. Both the first transmission part and the second transmission part are configured as racks. A central gear is provided between the first transmission part and the second transmission part, and the central gear meshes with both the first transmission part and the second transmission part.

[0004] Although this technical solution can achieve micro-pressure operation, its structure is relatively complex, making assembly troublesome and costly. Therefore, a lid bead with manual venting function and a micro-pressure pot lid are provided to solve the above problems. Utility Model Content

[0039] It should be noted that the specific working process of the lid bead with manual venting function and the micro-pressure pot lid of this utility model is as follows: When manual venting is required, the knob 1312 is turned clockwise by hand to drive the pinion 1311 to rotate. The pinion 1311 drives the venting block 132 to rotate. At the same time, the hook 133 moves on the rack 1114 following the movement of the venting block 132, so that the baffle 1323 moves relative to the venting channel 1111. When the second vent hole 13231 on the baffle 1323 moves to the venting end of the venting channel 1111 and the first... When the first exhaust port 1212 is in place, the gas inside the pressure cooker is discharged into the outside atmosphere through the air inlet cover 14, the exhaust channel 1111, the second exhaust port 13231, and the first exhaust port 1212 in sequence, thus completing the exhaust operation. After the exhaust is completed, the knob 1312 is turned counterclockwise. The knob 1312 drives the exhaust baffle 132 to rotate through the pinion 1311 in sequence, so that the second exhaust port 13231 on the baffle 1323 is misaligned with the exhaust end of the exhaust channel 1111, thus completing the blocking operation of the exhaust channel 1111.
