The fixed pressing ring 30 is connected with the cap body 10 to fix the seal ring 20 between the cap body 10 and the fixed pressing ring 30. The fixed pressing ring 30 is located below the connecting portion 21 and outside the seal lip portion 22. The outer side wall of the fixed clamping ring 30 is provided with a step structure 31, and the downward turned edge 211 is clamped between the step structure 31 and the side wall of the cover body 10.

By applying the technical scheme of the embodiment, the sealing ring 20 is directly fixed on the cover body 10 through the fixing pressing ring 30, so that the sealing ring is safe and reliable. The sealing ring 20 comprises a connecting part 21 and a sealing lip part 22, and a lower flanging 211 is arranged at the outer edge of the connecting part 21. The downward turned edge 211 is sandwiched between the step structure 31 on the outer side wall of the fixed pressing ring 30 and the side wall of the cover body 10. And then the contact area of the sealing ring 20 and the cover body 10 is increased, the sealing effect is improved, and the problem that the sealing is unreliable and the cooking effect is influenced in the related art is effectively solved.

As shown in fig. 6, 13 and 14, a positioning ring 411 extending downward is disposed at the first connection hole 41, a positioning hole 212 for accommodating the positioning ring 411 is disposed at the connection portion 21, and the positioning hole 212 communicates with the second connection hole 42. The first connection hole 41 extends downward to form a positioning ring 411, increasing the height of the first connection hole 41. The first connection hole 41 is a countersunk hole, and the positioning ring 411 is used to leave a space for processing the countersunk hole. Meanwhile, the connecting portion 21 is provided with the positioning hole 212, and in the installation process, the positioning ring 411 is firstly clamped in the positioning hole 212, so that the positioning of the sealing ring 20 and the cover body 10 is facilitated, and the subsequent installation of the fastener is easier. As shown in fig. 4, 5, 13 and 14, the seal lip portion 22 includes a first lip portion 221 that engages with the top wall of the lid body 10 and a second lip portion 222 located below the first lip portion 221, and the thickness of the first lip portion 221 gradually decreases in a direction away from the second lip portion 222. The first lip 221 is engaged with the lid body 10, and the second lip 222 is engaged with the pot 50. In the process of pressing up, the first lip portion 221 is tightly attached to the lid body 10 under the action of pressure in the pot, and thus sealing between the first lip portion 221 and the lid body 10 in the cooking process is realized. The upper surface of the first lip portion 221 is attached to the lower surface of the lid body 10, and the thickness of the first lip portion 221 is gradually reduced in the direction away from the second lip portion 222, so that the sealing ring 20 can be better attached to the lower surface of the lid body 10 during assembly, and the sealing effect is improved.

As shown in fig. 4 and 5, the first lip portion 221 has a first end connected to the second lip portion 222 and a second end distant from the second lip portion 222, and a thickness i of the first end of the first lip portion 221 satisfies: i is more than or equal to 1.5mm and less than or equal to 2.5mm, and the thickness h of the second end of the first lip part 221 satisfies: h is more than or equal to 0.3mm and less than or equal to 1.0 mm. The thickness of the first lip portion 221 gradually decreases from bottom to top, so that the first lip portion 221 can be better attached to the lower surface of the lid body 10 during upward pressing, and meanwhile, the structure is simple and the processing is easy. Preferably, i is 2mm and h is 0.5 mm.

As shown in fig. 8, the first lip portion 221 is inclined upward in a free state, and an angle g between the lower surface of the first lip portion and the horizontal direction satisfies 10 ° to 60 °. The above dimensions make the first lip portion 221 pressed against the lid body 10 by its own elasticity during installation, resulting in a good sealing effect. Preferably, g is 35 °.

As shown in fig. 4, 5, 13 and 14, the second lip portion 222 includes a first arc-shaped section 2221 that cooperates with the fixed clamping ring 30. Correspondingly, the inner surface of the fixed clamping ring 30 is an arc-shaped surface matched with the first arc-shaped section 2221. The smooth transition between the first arc-shaped section 2221 and the arc-shaped surface enables the inner surface of the fixed pressing ring 30 to better abut against the first arc-shaped section 2221 when the cooker is pressed upwards, so that the sealing ring 20 can bear pressure better.

As shown in fig. 4, 5, 13 and 14, the second lip 222 includes a second arcuate section 2222 that engages the pan body 50. The outer surface of the second arc-shaped section 2222 is attached to the inner surface of the pot body 50, and in the process of pressing, under the action of pressure in the pot, the second arc-shaped section 2222 is pressed tightly against the inner surface of the pot body 50, so that sealing is realized.

As shown in fig. 4 and 5, the arc radius j of the second arc-shaped segment 2222 satisfies: j is more than or equal to 15mm and less than or equal to 30 mm. The size is set, so that the structure is simple and the processing is easy. Preferably, j is 22 mm.

As shown in fig. 13 and 14, the fitting height n between the second lip portion 222 and the pan body 50 satisfies: n is more than or equal to 5mm and less than or equal to 10 mm. The arrangement of the attaching height n enables the sealing ring 20 and the pot body 50 to be overlapped in a certain height direction, and in the pressure cooking process, the sealing ring 20 cannot be extruded out of the pot body 50 due to the pressure in the pot, so that the sealing effect in the pressure cooking process is ensured. The size of the sealing ring 20 is reasonable and the sealing ring has good sealing effect. Preferably, n is 7.5 mm.

As shown in fig. 13 and 14, the interference dimension f of the second arc-shaped section 2222 with the pan body 50 satisfies: f is more than or equal to 0.2mm and less than or equal to 0.8 mm. Select less interference fit, make sealing washer 20 and the laminating of pot body 50 minisphere, above-mentioned size setting makes when the user closes lid body 10 soon, and sealing washer 20 and pot body 50 friction are less, convenience of customers' use. Meanwhile, the small-range fit of the sealing ring 20 and the pot body 50 is also beneficial to the upward pressure in the pot. Preferably, f is 0.5 mm.

As shown in fig. 4 and 5, the thickness m of the second arcuate section 2222 satisfies: m is more than or equal to 1.5mm and less than or equal to 2.5 mm. The size setting makes the sealing ring 20 take pressure bearing capacity and production cost into consideration. It should be noted that, when m is smaller than 1.5mm, the pressure-bearing requirement of the cooking utensil in the pressure cooking process cannot be met. When m is greater than 2.5mm, although the seal ring 20 may have a better pressure-bearing capacity, it may also cause a waste of material. Preferably, m is 2 mm.

As shown in fig. 11 to 13, the present application further provides a cooking appliance, which includes a pot body 50, a pot body 60 and the above-mentioned lid assembly. The cover body assembly can solve the problem that sealing is unreliable and further cooking effect is influenced in the related art. Meanwhile, the sealing ring 20 and the fixed pressing ring 30 are simple in structure and good in sealing effect. The cooking appliance having the cover assembly also has the advantages.

In this embodiment, the cooking appliance includes an air fryer or an electric rice cooker or an electric pressure cooker or a multifunctional heating pot with functions of baking, cooking and cooking.
