Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pressure cooker accessories, and more specifically, it relates to a pressure cooker lid and a pressure cooker. Background Technology
[0002] As a kitchen cookware, the pressure cooker mainly utilizes the physical phenomenon that the boiling point of a liquid increases under higher pressure. By applying pressure to water, the water can reach a higher temperature without boiling, thus speeding up the cooking process. In high-altitude areas, the pressure cooker can avoid the problem of water boiling point decreasing and food not cooking properly. Current pressure cookers seal the lid and body using a rotating locking mechanism. This method is cumbersome and difficult to open, especially while cooking. Furthermore, it typically only locks the lid by rotating it relative to the cooker body, without any additional locking mechanism. Once the pressure inside the pressure cooker is released, the sudden pressure drop can easily cause the lid to loosen. Therefore, in daily use, when the pressure cooker is under high pressure and heating food, if the lid becomes loose, the hot food inside can easily splash out, posing a danger. Utility Model Content

Reference Figures 4-6 The button self-locking device 3 includes a button 31 located in the middle of the pressure shell 2. The button 31 includes a button cap 311. An inclined pressure platform 312 for pushing the left and right retaining plates 4 is located on both sides of the button cap 311. A central shaft 313 is located in the middle of the button cap 311. The central shaft 313 is inserted into a positioning seat 32. Longitudinally evenly distributed teeth 321 are located inside the insertion hole of the positioning seat 32. The ends of the teeth 321 are two-stage serrations 3211. A base 33 is connected to the bottom of the positioning seat 32. A spring 34 is provided between the positioning seat 32 and the button 31. To facilitate smoother operation, pulleys 6 are provided on the left and right retaining plates 4, and the pulleys 6 contact the inclined pressure platform 312.
[0023] The bottom of the central shaft 313 is movably mounted with a stop seat 35 via a claw and sliding groove structure. An upper toothed ring 36 and a lower toothed ring 37 are threaded through the central shaft 313. The stop seat 35 is stepped. The lower toothed ring 37 is sleeved on the stop seat 35. The outer ring of the upper toothed ring 36 is provided with a boss 362 for engaging in the slot 322 between the teeth 321 of the positioning seat 32. The lower end of the upper toothed ring 36 is provided with teeth 361, which are consistent with the saw teeth 3211 and are staggered. The lower toothed ring 37 is provided with helical teeth 371 that partially mesh with the teeth 361.
[0024] A tension spring 5 is provided between the left and right buckle plates 4 and the positioning seat 32. To facilitate installation, hooks for installing the tension spring 5 are provided on the left and right buckle plates 4 and the positioning seat 32.
[0025] To prevent misalignment during installation, the bottom of the central shaft 313 is provided with a longitudinal strip groove 3131 and a positioning boss 3132.

[0029] Reference Figure 8This is a cross-sectional view of the pressure cooker in the locked state of this utility model. Pressing button 31 again will push the lower gear ring 37 downward. The helical teeth 371 of the lower gear ring 37 will slide along the meshing high-position sawtooth 3211 to the low-position sawtooth 3211. Under the action of the inclined plane, after the lower gear ring 37 rotates at a certain angle, the helical teeth 371 on the lower gear ring 37 will move into the slot 322 between the locking teeth 321. The button 31 will be reset under the action of the spring 34. The central shaft 313 will drive the upper gear ring 36 and the lower gear ring 37 to move upward through the stop seat 35. The upper teeth 361 of the upper gear ring 36 and the helical teeth 371 on the lower gear ring 37 will mesh. At this time, the button cap 311 will drive the inclined pressure platforms 312 on both sides to move upward. The left and right buckle plates 4 will be released from the restriction of the inclined pressure platforms 312. Under the action of the tension spring 5, the left and right buckle plates 4 will retract inward, and the pot lid can be locked.
[0030] This product allows for convenient and quick opening and closing of the pot lid by pressing the button 31 in the middle of the pressure shell 2. When the button 31 is pressed once, the inclined pressure plates 312 on both sides of the button 31 move downward, controlling the left and right latch plates 4 to move outward, thus opening the pot lid. Pressing the button 31 again moves the inclined pressure plates 312 on both sides of the button 31 upward, and the left and right latch plates 4 are released from the restriction of the inclined pressure plates 312. Under the action of the tension spring 5, the left and right latch plates 4 retract inward, thus locking the pot lid. This product is simple to operate and highly safe.
