[0030] As Figure 1 , Figure 2 and Figure 5 shown, the present application provides a cover assembly, the first embodiment of the cover assembly of the present application comprises: a cover body 10, a pot opening sealing ring 20; the cover body 10 has a cover top wall 11 and a cover side wall 12 located outside the cover top wall 11, the cover top wall 11 has a limiting section 111, the limiting section 111 is connected with the cover side wall 12; the pot opening sealing ring 20 comprises a mounting ring body 21, the mounting ring body 21 is limitedly matched with the limiting section 111 to limit the movement of the pot opening sealing ring 20 towards the cover top wall 11, the outer side wall 211 of the mounting ring body 21 is interference-fitted with the inner surface of the cover side wall 12 to limit the pot opening sealing ring 20 from separating from the cover body 10.

[0031] The lid body 10 is used to cover the pot body to form a cooking cavity capable of accommodating food. The lid body 10 has a lid top wall 11 and a lid side wall 12 located outside the lid top wall 11. The lid top wall 11 has a limiting section 111 connected with the lid side wall 12. The pot opening sealing ring 20 is arranged on the lid body 10. When the lid body 10 is covered with the pot body, the pot opening sealing ring 20 can be sealingly arranged at the pot opening of the pot body, so that the cooking cavity is kept in a sealed state, thereby ensuring that the cooking cavity can be pressurized and kept in a high-pressure state, and thus the food can be quickly cooked. When the lid body 10 is covered with the pot body, the bottom of the mounting ring body 21 abuts against the pot body, and the top of the mounting ring body 21 is limited by the limiting section 111 to limit the movement of the pot opening sealing ring 20 towards the lid top wall 11, thereby ensuring that the mounting ring body 21 is kept in a proper position. When the lid is opened, the outer side wall 211 of the mounting ring body 21 is in interference fit with the inner surface of the lid side wall 12, thereby limiting the disengagement of the pot opening sealing ring 20 from the lid body 10, and thus ensuring that the pot opening sealing ring 20 will not easily disengage from the lid body 10 when the lid is opened, and ensuring the stable connection of the pot opening sealing ring 20 and the lid body 10. When the user needs to install or dismount the pot opening sealing ring 20, compared with the related art in which an additional mounting structure is used to connect the pot opening sealing ring and the lid body, the user can directly use both hands to install or dismount the pot opening sealing ring 20 of the present embodiment, so that the user can conveniently clean the pot opening sealing ring 20, and the user experience is improved. In addition, since no additional mounting structure is needed, the manufacturing cost of the lid assembly is saved. Therefore, the technical solution of the present embodiment can effectively solve the problem that the lid assembly in the related art cannot balance the cost and user experience.

[0032] It should be noted that, in the present embodiment, the interference fit between the outer side wall 211 of the mounting ring body 21 and the inner surface of the lid side wall 12 means that the part of the outer side wall 211 of the mounting ring body 21 in contact with the inner surface of the lid side wall 12 is in interference fit with the inner surface of the lid side wall 12, thereby ensuring the stable connection of the pot opening sealing ring 20 and the lid body 10.

[0033] As Figure 1 , Figure 2 and Figure 5As shown, the interference amount between the mounting ring body 21 and the cover sidewall 12 is greater than 0 and less than or equal to 0.5 mm. Specifically, the interference amount meeting the above requirements, on the one hand, ensures that the user only needs to use small force to complete the installation and removal operation of the pot opening sealing ring 20, and the pot opening sealing ring 20 and the cover body 10 are not too tightly matched, and on the other hand, the pot opening sealing ring 20 and the cover body 10 can be stably connected, so that when the user opens the cover, the pot opening sealing ring 20 will not easily separate from the cover body 10. The interference amount between the mounting ring body 21 and the cover sidewall 12 can be 0.1 mm, 0.2 mm, 0.28 mm, 0.32 mm, 0.4 mm, 0.45 mm or 0.5 mm.

[0034] It should be noted that the "interference fit between the outer sidewall 211 of the mounting ring body 21 and the inner surface of the cover sidewall 12" refers to the case where the mounting ring body 21 and the cover body 10 are coaxially arranged, the radius of the mounting ring body 21 is greater than the distance from the cover sidewall 12 to the symmetry axis of the cover body 10, so that the outer sidewall 211 of the mounting ring body 21 can be interference fit with the inner surface of the cover sidewall 12.

[0035] As shown in Figure 1 , Figure 2 and Figure 5 , the outer sidewall 211 of the mounting ring body 21 is provided with a pressure relief groove 212. Specifically, when the pressure in the cooking cavity is too high and exceeds the preset value, the pressure relief groove 212 allows the gas in the cooking cavity to pass through the bottom of the pot opening sealing ring 20, then pass through the pressure relief groove 212 to be discharged from the upper cover of the cover assembly (located above the cover body 10) to the outside of the cover assembly, avoiding the safety hazard caused by the high pressure in the cooking cavity, and ensuring the safety of the user.

[0036] As shown in Figure 2 , the number of pressure relief grooves 212 is greater than or equal to 4 and less than or equal to 12. Specifically, a plurality of pressure relief grooves 212 are arranged at intervals along the circumferential direction of the mounting ring body 21. In this way, on the one hand, the overall weight of the pot opening sealing ring 20 can be reduced, and on the other hand, the area of the outer sidewall of the mounting ring body 21 can be ensured to be large enough, so that the contact area between the mounting ring body 21 and the inner surface of the cover sidewall 12 is large enough, and the stable connection between the pot opening sealing ring 20 and the cover body 10 is ensured. The number of pressure relief grooves 212 can be 4, 6, 7, 8, 10, 11 or 12.

[0037] As shown in Figure 2As shown, the width of the pressure relief groove 212 along the circumferential direction of the mounting ring 21 is greater than or equal to 4 mm and less than or equal to 10 mm. This design ensures the air release capacity of the pressure relief groove 212, thereby guaranteeing user safety. The width of the pressure relief groove 212 along the circumferential direction of the mounting ring 21 can be 4 mm, 5.3 mm, 6.7 mm, 7.5 mm, 8.6 mm, or 10 mm.

[0038] like Figure 1 As shown, a movable stop rod head 13 is provided on the side wall 12 of the lid. The stop rod head 13 can cooperate with the stop of the mounting ring 21 to prevent the pot opening sealing ring 20 from detaching from the lid body 10. Specifically, when the user opens the lid, the stop rod head 13 is located at the inward extreme position. At this time, the stop rod head 13 cooperates with the stop of the mounting ring 21 to prevent the pot opening sealing ring 20 from detaching from the lid body 10, thereby further ensuring that the pot opening sealing ring 20 will not detach from the lid body 10 when the lid is opened. When the lid assembly is closed, the stop rod head 13 will move to a position where it will not interfere with the pot opening sealing ring 20.

[0039] like Figure 5 As shown, the thickness D1 of the mounting ring 21 is greater than or equal to 2mm and less than or equal to 5mm, and the width D2 of the mounting ring 21 is greater than or equal to 3mm and less than or equal to 12mm. This design ensures that the pot opening sealing ring 20 has a certain rigidity, preventing it from bending during installation and avoiding incomplete contact with the lid side wall 12 due to bending. Furthermore, it ensures that the outer wall of the mounting ring 21 is sufficiently large, guaranteeing a stable connection between the pot opening sealing ring 20 and the lid body 10. The thickness D1 of the mounting ring 21 can be 2mm, 3.2mm, 3mm, 4.6mm, or 5mm; the width D2 of the mounting ring 21 can be 3mm, 4.6mm, 7.8mm, 10.5mm, or 12mm.

[0040] In addition, the material of the pot opening sealing ring 20 is silica gel. The pot opening sealing ring 20 made of silica gel has many advantages. Silica gel can withstand a wide temperature range, and can generally remain stable between -40 DEG C and 230 DEG C. This means that in a high-pressure cooking environment, the pot opening sealing ring 20 made of silica gel can maintain its shape and sealing performance without deforming or hardening due to high temperature, ensuring the sealing effect during cooking; in addition, silica gel has excellent elasticity, and even under long-term high pressure and high temperature conditions, it can maintain good elastic recovery ability. This feature allows the pot opening sealing ring 20 to tightly fit the pot opening when pressed, forming an effective seal, and easily releasing when the cover is opened; in addition, silica gel has strong resistance to acids, bases, and oils in most foods, and will not react with food ingredients, ensuring food safety and hygiene during cooking, while also extending the service life of the pot opening sealing ring 20; the surface of the pot opening sealing ring 20 made of silica gel is smooth and not easy to stain food residue, easy to clean, and the silica gel itself is also resistant to washing, can be washed in a dishwasher or soaked in a cleaning agent, and is easy to maintain daily.

[0041] As shown in Figure 2 and Figure 5 , the cover assembly can cooperate with the external pot body 1 to form a cooking space, and the pot opening sealing ring 20 further comprises a first lip 22 and a second lip 23 connected to the inner side wall of the mounting ring body 21, the first lip 22 and the second lip 23 are arranged in a spaced manner, the first lip 22 can abut against the cover top wall 11, and the second lip 23 can abut against the external pot body 1. Specifically, when pressed, the gas in the cooking cavity can press the first lip 22 so that the first lip 22 abuts against the cover top wall 11, and can press the second lip 23 so that the second lip 23 abuts against the external pot body 1, thereby enabling the pot opening sealing ring 20 to ensure the sealing performance of the cooking cavity.

[0042] In addition, as shown in Figure 3 and Figure 4 , the present application also provides a second embodiment of the cover assembly, which differs from the first embodiment in the number of pressure relief grooves 212 and the specific form of the pressure relief grooves 212. The pressure relief grooves 212 can be arranged as square holes or other forms.

[0043] As shown in Figure 5 , the present application also provides a cooking appliance, and an embodiment of the cooking appliance of the present application comprises a cover assembly, wherein the cover assembly is the cover assembly described above.
