[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] like Figures 1 to 12 As shown, this embodiment of the present invention provides a cover, which includes a cover body 10, at least two pressure-limiting valves 20, a pusher 30, and a mounting gasket 40. The mounting gasket 40 is used to support the exhaust pipes 11. The cover body 10 is provided with at least two exhaust pipes 11, and the pressure-limiting valves 20 are correspondingly disposed on the exhaust pipes 11. The pusher 30 is movably disposed on the cover body 10 and can push at least two pressure-limiting valves 20. The mounting gasket 40 is made of rigid material and has at least two first mounting holes 41. The exhaust pipes 11 are correspondingly inserted through the first mounting holes 41, and the at least two exhaust pipes 11 press the mounting gasket 40 onto the cover body 10.

[0039] When the upper cover provided by the embodiment is used, the at least two pressure limiting valves 20 are pushed by the pushing piece 30 when exhaust is needed after cooking is completed, so that the at least two pressure limiting valves 20 are opened simultaneously to exhaust, which can improve the exhaust speed of the cooking utensil. Since two pressure limiting valves 20 are used to exhaust simultaneously, the diameter of a single exhaust pipe does not need to be increased, and thus the problem of food overflow does not occur. Moreover, since the exhaust pipes 11 are arranged in the first mounting holes 41 of the mounting pad 40 one by one, and the at least two exhaust pipes 11 press the mounting pad 40 on the cover body 10, the at least two exhaust pipes 11 can be mounted and fixed through the same mounting pad 40, which can simplify the assembly structure. Compared with the mode in which each exhaust pipe of the at least two exhaust pipes is mounted through a separate pad, the assembly efficiency can be improved.

[0040] It should be noted that the at least two exhaust pipes 11 use the same mounting pad 40 to realize large plane support, so that the installation reference is in the same plane, and the double-valve or multi-valve exhaust is consistent.

[0041] As shown in Figure 1 and Figure 5 , the mounting pad 40 is provided with a top rod sealing piece 50 made of elastic material, and the pushing piece 30 has an initial position and a pushing position. When the pushing piece 30 moves from the initial position to the pushing position, the pushing piece 30 is in contact with the top rod sealing piece 50 and pushes the at least two pressure limiting valves 20 through the top rod sealing piece 50. The top rod sealing piece 50 made of elastic material can provide better sealing effect to prevent pressure leakage in the non-exhaust state.

[0042] Specifically, the top rod sealing piece 50 can isolate water droplets or soup during exhaust, to prevent water droplets or soup from flowing into the inside of the upper cover.

[0043] Among them, the elastic material of the top rod sealing piece 50 is selected, such as silicone or food-grade rubber, which not only improves the sealing performance, but also ensures the safety of the material, and is suitable for the cooking environment directly contacting food.

[0044] As shown in Figure 2 , the top rod sealing piece 50 is located between the two adjacent exhaust pipes 11, and is located on the side away from the upper cover handle 18 of the center line of the two exhaust pipes 11, and the overall assembly structure is more compact. When the two pressure limiting valves 20 are pushed up, the respective inclinations between the two pressure limiting valves 20 have an included angle of 30° to 90°. The two top rod sealing pieces 50 and the two exhaust pipes 11 are symmetrically arranged with respect to the front-rear direction center line of the upper cover 10, and the stress of the pushing piece 30 is relatively balanced.

[0045] In this embodiment, at least two top rod sealing pieces 50 are arranged on the mounting gasket 40, and the top rod sealing pieces 50 are arranged in one-to-one correspondence with the pressure limiting valves 20. When the pushing piece 30 moves from the initial position to the pushing position, the pushing piece 30 contacts the two top rod sealing pieces 50 and pushes at least two pressure limiting valves 20 through the two top rod sealing pieces 50. This multi-point sealing design can further improve the sealing performance and is suitable for high-pressure cooking environments.

[0046] In addition, in a high-pressure cooking environment, the multi-point sealing design can ensure that the pressure is uniformly released from different exhaust points when the pushing piece 30 is in action.

[0047] As shown in Figures 8 to 10 , the pushing piece 30 has at least two top rods 31, and the top rods 31 are arranged in one-to-one correspondence with the top rod sealing pieces 50. The top rods 31 extend into the corresponding top rod sealing pieces 50, and when the pushing piece 30 moves from the initial position to the pushing position, the upper end of the top rod 31 contacts the top wall of the top rod sealing piece 50 and pushes the corresponding pressure limiting valve 20 through the top wall of the top rod sealing piece 50. The cooperation between the top rod 31 and the top rod sealing piece 50 ensures the accuracy and stability of the pushing action, and is suitable for cooking scenarios that require precise control of exhaust volume.

[0048] Specifically, the precise cooperation between the top rod 31 and the top rod sealing piece 50 allows for fine-tuning of the exhaust volume, which is crucial for scenarios that require precise control of the cooking environment. For example, in the baking process, even small changes in pressure can affect the expansion and taste of the cake. With this design, the cooking appliance can more accurately control the exhaust process, ensuring that the food is cooked at the ideal pressure and temperature, thereby improving the quality and taste of the food.

[0049] As shown in Figure 3 , the mounting gasket 40 has a second mounting hole 42, and the top rod sealing piece 50 is arranged in the second mounting hole 42. This mounting method simplifies the assembly process of the top rod sealing piece 50, improves assembly efficiency, and reduces production costs.

[0050] In this embodiment, the mounting gasket 40 presses the top rod sealing piece 50 against the cover 10, which simplifies the assembly structure of the top rod sealing piece 50.

[0051] Specifically, by simplifying the assembly of the top rod sealing piece 50, this design not only reduces the complexity of the manufacturing process, but also reduces the time and labor costs required for assembly, which has significant economic advantages for large-scale production of cooking appliances.

[0052] As shown in Figure 5As shown, the top rod sealing piece 50 comprises a top plate 51 and an annular side plate 52, the upper end of the annular side plate 52 is connected with the edge of the top plate 51, the mounting gasket 40 is arranged to press the lower end of the annular side plate 52 on the cover body 10, and the annular side plate 52 has a wave-shaped structure 521 extending along the axial direction of the annular side plate 52. The design of the wave-shaped structure 521 increases the elasticity of the top rod sealing piece 50, which can better adapt to the movement of the push piece 30, and is suitable for the use of the cooking utensil under different pressure conditions, such as cooking conversion from low pressure to high pressure, to ensure the continuity and stability of pressure control.

[0053] As shown in the drawings, Figure 7 As shown, the mounting gasket 40 is provided with a first annular protrusion 43 surrounding the outer periphery of the first mounting hole 41. The design of the first annular protrusion 43 can improve the structural strength of the mounting gasket 40.

[0054] In this embodiment, the cover body 10 is provided with a second annular protrusion 12, which extends into the first annular protrusion 43 and is limitedly matched with the first annular protrusion 43. The cooperation of the second annular protrusion 12 and the first annular protrusion 43 can not only enhance the connection stability between the mounting gasket 40 and the cover body 10, but also improve the assembly accuracy of the mounting gasket 40.

[0055] Moreover, the limited cooperation design of the second annular protrusion 12 and the first annular protrusion 43 not only enhances the connection stability between the mounting gasket 40 and the cover body 10, but also improves the pressure resistance of the entire upper cover during high-pressure cooking. This design can effectively prevent the connection from loosening due to excessive internal pressure during cooking, ensuring the safety and durability of the cooking utensil during use. For high-pressure cooking equipment such as pressure cookers, this design can ensure the sealing and stability of the upper cover under long-term high-pressure cooking, prolong the service life of the equipment, and reduce maintenance costs.

[0056] As shown in the drawings, Figure 1 As shown, the cover body 10 is provided with a receiving groove 13, at least two exhaust pipes 11 are arranged through the bottom wall of the receiving groove 13, and the lower ends of at least two pressure limiting valves 20 are located in the receiving groove 13. The shape of the bottom wall of the receiving groove 13 is matched with the shape of the mounting gasket 40, and the mounting gasket 40 is pressed on the bottom wall of the receiving groove 13 by the at least two exhaust pipes 11. With the above structure, the receiving groove 13 is used to accommodate and shield part of the structure, which can not only reduce the thickness of the upper cover and facilitate the realization of the lightness of the upper cover, but also improve the integrity of the upper cover.

[0057] Specifically, the accommodating groove 13 is provided with a limiting rib 131 at the edge of the bottom wall of the accommodating groove 13, and the limiting rib 131 is in limiting fit with the side wall of the mounting gasket 40, that is, the shape of the bottom wall of the accommodating groove 13 is matched with the shape of the mounting gasket 40.

[0058] In the embodiment, one of the pushing piece 30 and the cover 10 is provided with a guide hole 32, and the other of the pushing piece 30 and the cover 10 is provided with a guide column 14 extending in the vertical direction, the guide column 14 is arranged in the guide hole 32, and a reset spring 60 is arranged between the pushing piece 30 and the cover 10. The arrangement of the guide hole 32 and the guide column 14 and the assistance of the reset spring 60 not only ensure the accurate movement of the pushing piece 30, but also realize the automatic reset of the pushing piece 30.

[0059] In the embodiment, the pushing piece 30 is designed with two guide holes 32 and a third mounting hole 33 for mounting the reset spring 60, and the inner lining of the corresponding cover 10 is provided with two guide columns 14 and a mounting column 15 for fixing the reset spring 60.

[0060] In the embodiment, the cover 10 includes a face cover 16 and a steel cover, the exhaust pipe 11 is connected between the face cover 16 and the steel cover, and the mounting gasket 40 is arranged on the face cover 16. The cover 10 further includes an inner lining 17 between the face cover 16 and the steel cover.
