Description

Technical Field

[0001] This utility model relates to the field of pressure cooker technology, specifically to a pressure cooker. Background Technology

[0002] A pressure cooker is a type of kitchen cookware. Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure, allowing water to reach a higher temperature without boiling, thus speeding up the cooking process. Pressure cookers are generally equipped with a pressure relief valve, which releases the pressure inside the pot after cooking, allowing for safe opening of the lid.

[0003] A search revealed that this utility model relates to the field of kitchenware, specifically a pressure cooker, and has been granted Chinese patent publication number CN 221265890 U. The pressure cooker includes a body with a lid. The lid has a vent at its top and a water-gas separator at its bottom, connected to the vent and equipped with a valve. This utility model provides a pressure cooker that separates water and gas during the venting process, preventing water from escaping through the vent and ensuring safety and reliability.

[0004] The pressure cooker described in the aforementioned patent still has some shortcomings. Because the existing pressure cooker lids are relatively simple in structure and cannot indicate the internal pressure value, it is difficult for users to judge the pressure level inside the pot. They can only rely on personal experience to open the lid to check, which can easily lead to the release of high-pressure steam due to opening the lid too early, affecting the cooking rate of the food and failing to meet the user's needs.

[0029] The pressure regulating valve assembly 5 includes a pressure regulating valve body 501 disposed within the valve seat body 4. A pressure regulating valve core 502 is disposed on the bottom side of the pressure regulating valve body 501. A pressure regulating spring 503 is disposed on the top of the pressure regulating valve core 502. The top of the pressure regulating spring 503 is connected to the pressure regulating valve body 501 through a spring fixing seat 504. An exhaust spring 505 is disposed on the outside of the pressure regulating valve body 501. A pressure regulating valve cap 506 is disposed on the top of the pressure regulating valve body 501. A valve cap decorative piece 507 is disposed on the pressure regulating valve cap 506. One side of the valve seat body 4 is connected to the pot lid 2 through a valve seat fixing post 508.

[0030] The indicator valve assembly 6 includes an indicator valve body 601 disposed within the valve seat body 4, an indicator valve core 602 disposed at the bottom of the indicator valve body 601, an indicator valve sealing ring 603 and an indicator valve O-ring 604 disposed on the outer side of the indicator valve core 602, an indicator valve spring 605 disposed between the indicator valve core 602 and the indicator valve body 601, an indicator cap 606 disposed at the top of the indicator valve body 601, an indicator valve decorative piece 607 disposed on the outer side of the indicator cap 606, and the middle part of the valve seat body 4 is connected to the pot lid 2 through a valve seat fixing nut 608.

[0031] The handle auxiliary component 7 includes a secondary handle body 701 disposed on the top side of the pot body 1, a secondary handle pot ear 702 disposed on the top of the side of the pot body 1, the secondary handle pot ear 702 being inserted into the secondary handle body 701, and a secondary handle heat-resistant detachment 703 disposed on the bottom side of the secondary handle body 701.

[0032] Example 2: The difference between this example and Example 1 is that a threaded groove is provided in the middle of the valve seat body 4.

[0033] This makes it easier for users to install the valve seat body 4 and the pot lid 2.

[0034] Example 3: The difference between this example and Example 1 is that the indicator valve sealing ring 603 and the indicator valve O-ring 604 are fitted together on the outside of the indicator valve core 602.

[0035] This makes the sealing ring 603 and the O-ring 604 of the indicator valve more tight on the outside of the indicator valve core 602.

[0036] Example 4: The difference between this example and Example 1 is that the indicator cap 606 is provided with three pressure indicator lines.

[0037] This allows for indication via three pressure indicator lines on the indicator cap 606, with the first white line representing the low pressure value, the second white line representing the high pressure value, and the third red line representing the pressure value of the check valve.

[0038] In this embodiment, the existing pressure cooker lids are relatively simple in structure and cannot indicate the internal pressure value of the pressure cooker. This makes it difficult for users to judge the pressure level inside the pot. They can only rely on personal experience to open the lid to check, which can easily lead to the release of high-pressure steam due to opening the lid too early, affecting the cooking rate of the food and failing to meet the user's needs.

[0039] In summary, in specific implementation, a pot lid 2 is provided on the pot body 1, and a handle assembly 3 is provided on the side of the pot body 1. The stop-open safety valve assembly 306 provided at the end of the upper handle body 301 of the handle assembly 3 is installed on the pot lid 2. The stop-open function of the stop-open safety valve assembly 306 can discharge the pressurized steam inside the pot body 1. The operation of the stop-open safety valve assembly 306 is achieved by the joint action of the drive disc 307, the stop-open tongue 308, the stop-open tongue spring 309, and the self-locking block 310.

[0040] A valve seat body 4 is also provided on the pot lid 2. A pressure regulating valve assembly 5 and an indicator valve assembly 6 are respectively provided on the valve seat body 4. The pressure regulating valve body 501 and the pressure regulating valve core 502 in the pressure regulating valve assembly 5 are installed inside the valve seat body 4. The bottom side of the pressure regulating valve core 502 extends to the top of the pot body 1, so that the high-pressure steam inside the pot body 1 can resist the pressure regulating valve core 502, thereby opening the pressure regulating valve body 501 and realizing automatic venting and pressure reduction.

[0041] The indicator cap 606 in the indicator valve assembly 6 is located on the top side of the indicator valve body 601. The bottom of the indicator valve body 601 also extends to the top of the pot body 1 through the indicator valve core 602. When the indicator valve core 602 is subjected to high pressure, it can push the indicator cap 606 on the top of the indicator valve body 601 upward, so that the indicator cap 606 gradually moves upward. The indicator cap 606 is provided with three pressure indicator lines, of which the first white line represents the low pressure value and the second white line represents the high pressure value.

[0042] The third red line represents the pressure value of the safety valve, and the normal working pressure value is set as follows: the low working pressure value is set to 60kPa±10%, and the high working pressure value is set to 100kPa. By observing the position of the indicator cap 606 when it moves upward, the user can accurately monitor the pressure inside the pot after the pot body 1 and the pot lid 2 are closed, so as to facilitate the user's timely opening operation and meet their usage needs.
