Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure cooking pots, and more specifically, it relates to a high-pressure cooking pot. Background Art

[0002] In the existing technology, a high-pressure cooking pot is a common kitchen utensil. It seals the pot lid to generate a relatively high pressure inside the pot, thereby increasing the boiling point of water to achieve rapid cooking. However, this device has certain limitations during use, especially in terms of pressure regulation.

[0003] Existing high-pressure cooking pots are usually equipped with a safety valve, which is a pressure relief device used to release some steam when the pressure inside the pot exceeds the safety limit to prevent the pot body from bursting due to excessive pressure. This design does improve the safety during use, but it also brings some inconveniences. Since the existing pressure cooker cannot adjust the pressure of pressure relief, once the pressure inside the pot exceeds the preset value, the safety valve will automatically start, resulting in a decrease in pressure. This non-adjustable pressure relief mechanism may affect the cooking effect, especially in recipes that require precise control of pressure. For example, some foods may require a higher pressure to ensure a short cooking time and the food is more tender, while the existing pressure cookers cannot meet this requirement.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present utility model provides a high-pressure cooking pot, which has the following beneficial effects:

[0017] 1. The pressure relief mechanism, through the configuration of the pot lid, adjustment pipe, fixed pipe, adjustment rod, fixed disk, adjustment disk, sealing mechanism and adjustment mechanism, realizes the precise control of the pressure inside the high-pressure cooking pot. When the pressure inside the pot exceeds the set value, by rotating the adjustment disk to drive the indicator line to rotate to determine the pressure magnitude, the adjustment rod rotates relative to the fixed pipe, driving the sealing disk to push upward and press on the unlocking sleeve, causing the unlocking sleeve to move and compress the spring, thus completing the adjustment process. When complete sealing is required, by rotating the threaded pipe, the sealing sleeve is pressed on the fixed ring to close the exhaust pipe and complete the closing process. This design enables users to adjust the pressure of pressure relief according to actual needs, improving the usage effect and safety of the high-pressure cooking pot.

[0018] 2. The adjustment mechanism includes a fixed ring and a spring. By rotating the adjustment disk to determine the pressure magnitude, the adjustment rod rotates relative to the fixed pipe, driving the sealing disk to push upward and press on the unlocking sleeve, causing the unlocking sleeve to move and compress the spring. This design enables users to adjust the pressure of pressure relief according to actual needs, improving the usage effect and safety of the high-pressure cooking pot.

[0019] 3. The sealing mechanism includes a threaded pipe, a rotating disk, a sealing sleeve and an exhaust pipe. By rotating the threaded pipe, the sealing sleeve is pressed on the fixed ring to close the exhaust pipe and complete the closing process. When the pressure inside the pot exceeds the elastic force of the spring, the unlocking sleeve will slide upward to unseal the seal between the sealing disk and the unlocking sleeve, and the steam is discharged through the exhaust pipe to complete the pressure relief process. This design ensures that the high-pressure cooking pot can be effectively sealed and pressure-relieved when needed, improving the safety and reliability of the equipment. Description of the Drawings

[0029] Please refer to Figures 1-5, A high-pressure cooking pot, comprising a pot body 1, on which a pressure relief mechanism is provided. The pressure relief mechanism includes a pot lid 2, an adjustment pipe 3, a fixed pipe 4, an adjustment rod 5, a fixed disk 6, an adjustment disk 7, a sealing mechanism and an adjustment mechanism. The pot lid 2 is installed on the pot body 1. The adjustment pipe 3 is communicated with the pot lid 2. The fixed pipe 4 and the adjustment pipe 3 are coaxially arranged. The adjustment rod 5 is rotatably connected inside the fixed pipe 4. The fixed disk 6 is coaxially installed on the fixed pipe 4. A plurality of scales 8 are equidistantly arranged on the side wall of the fixed disk 6. An adjustment disk 7 is installed on the adjustment rod 5. An indicating line 9 is provided on the side wall of the adjustment disk 7, and the adjustment disk 7 is attached to the fixed disk 6. The sealing mechanism and the adjustment mechanism are installed on the adjustment pipe 3. The adjustment mechanism includes a fixed ring 10 and a spring 11. The fixed ring 10 is installed inside the adjustment pipe 3. The spring 11 is connected to the fixed ring 10. A plurality of guide bars 12 are equidistantly arranged on the inner wall of the adjustment pipe 3. A release sleeve 13 is slidably arranged on the inner wall of the adjustment pipe 3. The guide bars 12 are slidably connected to the release sleeve 13. The spring 11 is connected to the release sleeve 13. A threaded sleeve 14 is provided on the fixed pipe 4 in a threaded manner. A sealing disk 15 is coaxially arranged on the threaded sleeve 14. The sealing disk 15 is attached to the release sleeve 13. A conical head 16 is provided on the adjustment rod 5. A plurality of insertion rods 17 are provided on the conical head 16. The plurality of insertion rods 17 are respectively slidably connected to the sealing disk 15. The sealing mechanism includes a threaded pipe 18 and a rotating disk 19. The threaded pipe 18 is threadedly connected to the adjustment pipe 3. The rotating disk 19 is installed on the threaded pipe 18. The fixed pipe 4 is slidably connected inside the threaded pipe 18. A sealing sleeve 20 is provided on the outer wall of the threaded pipe 18. The sealing sleeve 20 is attached to the inner wall of the adjustment pipe 3. An exhaust pipe 21 is provided on the side wall of the adjustment pipe 3.

[0030] In this embodiment, when it is necessary to adjust the pressure of pressure relief, first, by rotating the adjustment disk 7, the rotation of the indicating line 9 can be driven. Then, the rotation angle can be determined through the scale 8 and the indicating line 9, so as to determine the magnitude of the pressure. Then, the adjustment rod 5 rotates relative to the fixed pipe 4. Since the insertion rod 17 is slidably connected to the sealing disk 15, the threaded sleeve 14 can be driven to rotate threadedly along the fixed pipe 4. Then, the sealing disk 15 can be pushed upward. Then, the sealing disk 15 presses on the release sleeve 13. Then, the release sleeve 13 moves along with it, so as to compress the spring 11, and thus the adjustment process is completed. When it is necessary to completely seal, by rotating the threaded pipe 18, the sealing sleeve 20 can be pressed on the fixed ring 10, and then the exhaust pipe 21 is closed, thus completing the closing process.

[0031] More specifically, when the pressure inside the pot exceeds the elastic force of the spring 11, then the release sleeve 13 will slide upward, thus unlocking the seal between the sealing disk 15 and the release sleeve 13. Then, the steam is discharged through the exhaust pipe 21, thus completing the pressure relief process.

[0032] In summary, when the overall equipment is in use or running: when it is necessary to adjust the pressure of the pressure relief, first, the indicator line 9 can be driven to rotate by rotating the adjusting disk 7, and then the rotation angle can be determined by the scale 8 and the indicator line 9 to determine the size of the pressure, and then the adjusting rod 5 is rotated relative to the fixed tube 4. Since the insertion rod 17 is slidably connected to the sealing disk 15, the threaded sleeve 14 can be driven to rotate along the thread of the fixed tube 4, and then the sealing disk 15 can be pushed upward, and then the sealing disk 15 is pressed on the unfastening sleeve 13, and then the unfastening sleeve 13 moves with it, thereby compressing the spring 11, and thus completing the adjustment process. When a complete seal is required, the sealing sleeve 20 can be pressed on the fixed ring 10 by rotating the threaded tube 18, and then the exhaust pipe 21 is closed, thereby completing the sealing process. When the pressure in the pot exceeds the elastic force of the spring 11, the unfastening sleeve 13 will slide upward, thereby unfastening the seal between the sealing disk 15 and the unfastening sleeve 13, and then the steam is discharged through the exhaust pipe 21, thereby completing the pressure relief process.
