It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0044] The present application provides a cover assembly, Figures 1 to 16 A structural schematic diagram of a first embodiment of a cover assembly according to the present application is shown.

[0045] like Figure 1 , Figure 5 and Figure 7The cover assembly of this embodiment includes an upper cover 10, an inner cover 20, a sealing turntable 30, a mounting seat 40 and an elastic push-up member 50. The upper cover 10 has an exhaust port 101; the inner cover 20 is rotatably arranged below the upper cover 10, and the inner cover 20 includes a cover body 21 and an exhaust structure 22 arranged on the cover body 21; the sealing turntable 30 is arranged between the upper cover 10 and the inner cover 20 and can rotate synchronously with the inner cover 20, the exhaust structure 22 is penetrated through the sealing turntable 30, and the sealing turntable 30 is sealed with the upper cover 10 and the exhaust structure 22; the mounting seat 40 is arranged between the upper cover 10 and the inner cover 20 and is located below the sealing turntable 30; the elastic push-up member 50 is arranged between the sealing turntable 30 and the mounting seat 40 and applies a push-up force toward the upper cover 10 to the sealing turntable 30 so that the sealing turntable 30 remains in a state of sealing with the upper cover 10.

[0046] By applying the technical solution of this embodiment, the upper cover 10 and the inner cover 20 form the main part of the cover body assembly, the inner cover 20 includes a cover body 21 and an exhaust structure 22 arranged on the cover body 21, the exhaust structure 22 can rotate synchronously with the cover body 21, the sealing turntable 30 is arranged between the upper cover 10 and the inner cover 20 and can rotate synchronously with the inner cover 20, the steam exhausted through the exhaust structure 22 will be directly discharged to the outside of the cover body assembly through the exhaust port 101 or form condensed water at the sealing turntable 30, because the sealing turntable 30 is sealed with the upper cover 10 and the exhaust structure 22, it can prevent steam or condensed water from entering between the upper cover 10 and the inner cover 20 from the connection between the sealing turntable 30 and the exhaust structure 22 or from the connection between the sealing turntable 30 and the upper cover 10. In addition, the cover assembly also includes a mounting seat 40 and an elastic abutment 50. The mounting seat 40 is used to mount the sealing disc 30. The elastic abutment 50 is disposed between the sealing disc 30 and the mounting seat 40 and abuts against the sealing disc 30 upward, so that the sealing disc 30 can always abut against the upper cover 10 to maintain the sealing between the two. That is, by disposing the sealing disc 30 and the elastic abutment 50, the exhaust structure 22 can be set away from the center of the cover assembly, and steam and condensed water can be prevented from entering between the upper cover 10 and the inner cover 20. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the eccentric setting of the pressure limiting valve makes it easy for water vapor to enter between the upper cover and the inner cover.

[0047] In this embodiment, the elastic support member 50 has a certain floating ability in the up and down directions. When the upper cover 10 or the sealing turntable 30 itself has a certain processing or installation error, the floating ability of the elastic support member 50 can compensate for these errors, thereby ensuring the sealing effect between the sealing turntable 30 and the upper cover 10.

[0048] like Figure 1 , Figure 5 and Figure 6As shown, the upper cover 10 includes a surface cover 12 and an inner liner 13, the inner liner 13 is arranged between the surface cover 12 and the cover body 21, the top of the sealing turntable 30 is sealed with the surface cover 12, and the mounting seat 40 is located between the inner liner 13 and the surface cover 12 and connected to the inner liner 13 and / or the surface cover 12. The mounting seat 40 is connected to the inner liner 13 and / or the surface cover 12, so that the position of the mounting seat 40 and the upper cover 10 can be relatively fixed, and then the sealing turntable 30 will not change its position in the up and down direction with the pressure increase or decrease in the cooking cavity, thereby ensuring the sealing effect between the sealing turntable 30 and the upper cover 10.

[0049] It should be noted that the above-mentioned “mounting seat 40 is connected to the lining 13 and / or the surface cover 12” means that the mounting seat 40 and the lining 13 and / or the surface cover 12 are an integrally formed structure, or the mounting seat 40 is an independently arranged structure and is connected to the lining 13 and / or the surface cover 12 through a connecting member.

[0050] like Figure 1 and Fig.16 As shown, in the present embodiment, the cover assembly further includes a cover 14, and a mounting port 121 is provided on the face cover 12. The cover 14 is detachably provided at the mounting port 121 and is capable of covering the mounting port 121. The exhaust port 101 is formed on the cover 14 or between the cover 14 and the face cover 12. The cover 14 is capable of covering the sealing turntable 30 and the exhaust structure 22 to ensure the aesthetics of the cover assembly. During the exhaust process, part of the steam discharged through the upper end of the exhaust structure 22 is condensed on the sealing turntable 30 to form condensed water, and part of the steam is discharged from the exhaust port 101 to the external space.

[0051] In the present application, the rotating structure (i.e., the sealing turntable 30) is arranged between the surface cover 12 and the inner cover 20, and a cover 14 is arranged above the rotating structure to cover it. The cover 14 does not need to rotate synchronously with the inner cover 20 and the sealing turntable 30, so that the appearance above the cover body assembly is consistent, thereby improving the user experience.

[0052] Of course, in an embodiment not shown in the figure, it is also possible not to provide a cover and directly provide the exhaust port on the cover.

[0053] like Figure 5 as well as Figures 7 to 10 As shown, the mounting seat 40 is provided with a receiving recess 41, and the elastic push member 50 is arranged in the receiving recess 41. The elastic push member 50 is arranged on the mounting seat 40, which has the advantage of simple structure.

[0054] like Figure 7As shown, the mounting seat 40 includes a support plate body 43 and a connecting arm 44 disposed outside the support plate body 43. The support plate body 43 includes a bottom plate 431 and a vertical plate 432 disposed outside the bottom plate. The bottom plate 431 is provided with an escape opening 433 for escaping the exhaust structure 22. The accommodating recess 41 is disposed on the vertical plate 432. The connecting arm 44 is connected to the vertical plate 432. In this embodiment, the mounting seat 40 is connected to the cover 12 by screws penetrating the connecting arm 44 and the cover 12. Figure 5 as well as Figures 7 to 11 As shown, a slide groove 31 is provided on the lower surface of the sealing rotary disk 30. When the sealing rotary disk 30 rotates, the slide groove 31 moves so that the elastic abutting member 50 abuts against different positions of the groove bottom wall of the slide groove 31. By providing the slide groove 31 matched with the elastic abutting member 50 on the lower surface of the sealing rotary disk 30, it is convenient to position the sealing rotary disk 30 and the mounting seat 40 when assembling the cover assembly; it can also achieve guidance during the rotation of the sealing rotary disk 30.

[0055] like Figure 5 as well as Figures 7 to 12 As shown, the inner cover 20 has a closing position and an opening position, the sealing turntable 30 has a closing sealing position corresponding to the closing position and an opening sealing position corresponding to the opening position, the bottom wall of the slide groove 31 has an intermediate abutting surface 311 and a closing abutting surface 312 and an opening abutting surface 313 arranged at both ends of the intermediate abutting surface 311, the intermediate abutting surface 311 is convexly arranged relative to the closing abutting surface 312 and the opening abutting surface 313, when the sealing turntable 30 rotates from the opening sealing position to the closing sealing position, the opening abutting surface 313, the intermediate abutting surface 311 and the closing abutting surface 312 are abutted and matched with the elastic abutting member 50 in turn. The opening cover abutment surface 313 and the closing cover abutment surface 312 are lower than the middle abutment surface 311. Thus, when the elastic abutment 50 cooperates with the middle abutment surface 311 (that is, when the inner cover 20 rotates from the opening cover position to the closing cover position or from the closing cover position to the opening cover position), the abutment force applied by the elastic abutment 50 to the sealing turntable 30 is relatively small. Thus, the resistance of the elastic abutment 50 relative to the upper cover 10 is small, which makes the user's operation feel better. When the elastic abutment 50 cooperates with the opening cover abutment surface 313 or the closing cover abutment surface 312 (that is, when the inner cover 20 is in the opening cover position or the closing cover position), the abutment force applied by the elastic abutment 50 to the sealing turntable 30 is relatively large, thereby ensuring the sealing effect between the elastic abutment 50 and the upper cover 10.

[0056] Preferably, the convex height of the highest point of the middle abutment surface 311 relative to the opening cover abutment surface 313 and the closing cover abutment surface 312 is greater than or equal to 0.5 mm, so as to reduce the rotational resistance and friction when the inner cover 20 rotates from the opening cover position to the closing cover position or from the closing cover position to the opening cover position.

[0057] Specifically, in the present embodiment, when the inner cover 20 is in the closed position and the cooking utensil is cooking, steam is discharged through the exhaust structure 22, and the elastic abutting member 50 enables the sealing turntable 30 to reliably abut against the lower surface of the upper cover 10, so as to prevent steam and condensed water formed by the steam from entering between the inner cover 20 and the upper cover 10 through the connection between the upper cover 10 and the sealing turntable 30; when the inner cover 20 is in the open position, since the user will flip the cover assembly to open the cover, the elastic abutting member 50 enables the sealing turntable 30 to reliably abut against the lower surface of the upper cover 10, so as to prevent condensed water from entering between the inner cover 20 and the upper cover 10 through the connection between the upper cover 10 and the sealing turntable 30 when the user flips the cover assembly; when the inner cover 20 is switched between the open position and the closed position, the sealing turntable 30 can be sealed with the upper cover 10 to ensure the sealing effect, and the sealing turntable 30 may not be sealed with the upper cover 10, so as to reduce the operating resistance when the user drives the inner cover 20 to rotate, and the hand feel is better.

[0058] like Figures 7 to 10 As shown, the elastic abutting member 50 includes a push rod 51 movably disposed in the accommodating recess 41 along the up-down direction and an elastic member 52 disposed between the push rod 51 and the bottom wall of the accommodating recess 41. The push rod 51 can abut against the lower surface of the sealing rotary disk 30 (specifically, the top wall of the slide groove 31) under the action of the elastic member 52, and press the sealing rotary disk 30 on the lower surface of the upper cover 10 to ensure the sealing effect between the sealing rotary disk 30 and the upper cover 10.

[0059] When the sealing rotary disk 30 and the mounting seat 40 are not assembled, the push rod 51 protrudes upward from the top surface of the accommodating recess 41 , and preferably, the protruding height is greater than or equal to 2 mm.

[0060] like Fig. 9 and Fig.10 As shown, the lower end of the ejector rod 51 has a first clamping member 53 and a second clamping member 54 arranged at intervals, and the side wall of the accommodating recess 41 is provided with a first clamping groove 411 and a second clamping groove 412. The first clamping member 53 is movably clamped in the first clamping groove 411 along the up-down direction, and the second clamping member 54 is movably clamped in the second clamping groove 412 along the up-down direction. The first clamping groove 411 can guide the first clamping member 53 and prevent the first clamping member 53 from detaching upwards, and the second clamping groove 412 can guide the second clamping member 54 and prevent the second clamping member 54 from detaching upwards, thereby ensuring the stability of the movement of the ejector rod 51 and limiting the ejector rod 51 from detaching upwards from the accommodating recess 41.

[0061] like Fig. 9As shown, the first clamp 53 includes a clamp arm 531 and a clamp block 532 arranged at the lower end of the clamp arm 531; similarly, the second clamp 54 also includes a clamp arm and a clamp block arranged at the lower end of the clamp arm. When installing the ejector 51, the clamp arm 531 of the first clamp 53 and the clamp arm of the second clamp 54 have a certain elasticity and can shrink inwards, so that the first clamp 53 and the second clamp 54 can enter the accommodating recess 41. When the clamp block 532 of the first clamp 53 moves to the first slot 411 and the clamp block of the second clamp 54 moves to the second slot 412, the two clamp arms expand outwards under the action of their own elasticity, so that the two clamp blocks are respectively engaged with the corresponding slots. The above arrangement facilitates the operation of installing the ejector 51 into the accommodating recess 41 and has the advantage of simple structure.

[0062] like Fig. 9 and Fig.10 As shown, a guide slope 413 is provided on the side wall of the receiving recess 41, and the guide slope 413 is located above the first card slot 411. From top to bottom, the guide slope 413 extends toward the inner side of the receiving recess 41. Similarly, a guide slope is also provided above the receiving recess 41 corresponding to the second card slot 412. The provision of the two guide slopes makes the opening of the receiving recess 41 larger, which is convenient for aligning the ejector 51 with the receiving recess 41. The guide slope 413 above the first card slot 411 can guide and position the first card member 53, so that the first card member 53 can move smoothly to the first card slot 411; the guide slope above the second card slot 412 can guide and position the second card member 54, so that the second card member 54 can move smoothly to the second card slot 412.

[0063] like Figures 7 to 10 As shown, a guide column 42 is provided on the bottom wall of the accommodating recess 41, and an elastic member 52 is sleeved on the guide column 42. Specifically, in this embodiment, the elastic member 52 is a compression spring, and the elastic member 52 is sleeved on the guide column 42, which can position the elastic member 52 and ensure the direction of the force applied by the elastic member 52 to the push rod 51, thereby ensuring the smooth movement of the push rod 51 and the push-up effect on the sealing rotary disk 30.

[0064] like Fig. 9 As shown, the top of the push rod 51 has an arc-shaped abutting surface 511. Since the sealing rotary disk 30 moves in the lateral direction relative to the push rod 51, the arc-shaped abutting surface 511 is provided on the top of the push rod 51 to reduce the friction between the push rod 51 and the sealing rotary disk 30, so that the rotation of the sealing rotary disk 30 is smoother.

[0065] like Figure 7 and Fig.11As shown, the sealing turntable 30 has a plurality of slide grooves 31, and the cover assembly includes a plurality of elastic abutting members 50 arranged one by one corresponding to the plurality of slide grooves 31. By providing a plurality of slide grooves 31 and a plurality of elastic abutting members 50, the stability of the support for the sealing turntable 30 can be ensured.

[0066] Specifically, the above-mentioned "plurality" refers to two or more. In this embodiment, the number of the slide grooves 31 and the number of the elastic abutting members 50 are three. Fig.11 As shown, in this embodiment, the centers of the plurality of slide grooves 31 are arranged to form an annular structure, and the annular structure is not limited to a circle, and may also be an ellipse or other shapes.

[0067] like Figure 5 , Figure 6 as well as Figures 13 to 15 As shown, the sealing turntable 30 includes a supporting turntable 32 and a sealing sheet 33 disposed above the supporting turntable 32, a sealing convex ring 331 is disposed on the sealing sheet 33, and a sealing convex rib 11 is disposed on the lower surface of the upper cover 10, and the sealing convex rib 11 is abutted against the sealing convex ring 331. The sealing sheet 33 is sealed with the upper cover 10 through the sealing convex ring 331, so that the middle part of the sealing sheet 33 can form a concave water collecting part to collect condensed water and food residues and other dirt generated during the cooking process, so as to prevent condensed water and food residues and other dirt from remaining on the sealing surface (i.e., the top surface of the sealing convex ring 331) to affect the smoothness of the rotation of the sealing turntable 30 and the sealing effect between the sealing turntable 30 and the upper cover 10. A sealing rib 11 is provided on the lower surface of the upper cover 10 to cooperate with the sealing convex ring 331, which can reduce the friction between the sealing convex ring 331 and the upper cover 10 when the sealing turntable 30 rotates, thereby ensuring the user's operating feel, and at the same time can reduce the wear of the sealing convex ring 331 to ensure the service life of the sealing turntable 30.

[0068] The sealing sheet 33 itself is a flexible structure, and can maintain a good sealing effect with the sealing rib 11 on the upper cover 10 . The sealing sheet 33 is supported by the supporting turntable 32 , so that the installation of the sealing turntable 30 is facilitated.

[0069] Specifically, the convex height of the sealing convex ring 331 is greater than or equal to 5 mm, so that the concave water collecting portion formed in the middle of the sealing sheet 33 has a sufficiently large water storage space.

[0070] like Figures 1 to 3As shown, the exhaust structure 22 includes an exhaust pipe 221 penetrating the cover body 21 and the bottom wall of the concave water collecting part, and a pressure limiting valve 222 arranged above the exhaust pipe 221, and the pressure limiting valve 222 is located in the concave water collecting part. During cooking, when the pressure inside the cooking cavity is increased or decreased, the cover body 21 will float up and down, thereby driving the exhaust structure 22 to float up and down. Since the sealing sheet 33 is a flexible structure, the bottom wall of the concave water collecting part can be deformed to adapt to the up and down floating of the exhaust structure 22, thereby avoiding the sealing turntable 30 being set as a structure that can float up and down.

[0071] Specifically, in this embodiment, the user can drive the cover body 21 to rotate by operating the operating member. The exhaust pipe 221 is fixedly disposed on the cover body 21 . When the cover body 21 rotates, the exhaust pipe 221 drives the sealing turntable 30 to rotate.

[0072] like Figure 1 , Figure 4 and Fig.11 As shown, in this embodiment, the exhaust structure 22 is a double exhaust valve structure, in which one exhaust valve is concentrically arranged with the cover body 21, and the other exhaust valve is eccentrically arranged with the cover body 21, and the avoidance opening 433 on the mounting seat 40 can avoid the exhaust structure 22.

[0073] The support turntable 32 is provided with two through holes for the two exhaust pipes 221 of the dual exhaust valve structure to pass through, one of which is concentrically arranged with the cover body 21, and the other is eccentrically arranged with respect to the cover body 21. When the cover body 21 rotates, the through hole and the exhaust valve concentrically arranged with respect to the cover body 21 remain in the same position, and the exhaust valve of the through hole eccentrically arranged with respect to the cover body 21 moves along an arc track with the center of the cover body 21 as the arc center. Correspondingly, the sealing sheet 33 is also provided with two through holes corresponding to the dual exhaust valve structure.

[0074] That is, in this embodiment, the rotation center of the sealing rotary disk 30 is inside the sealing rotary disk 30. Of course, in an embodiment not shown in the figure, the rotation center of the sealing rotary disk may also be outside the sealing rotary disk.

[0075] like Figures 5 to 7 as well as Fig.13As shown, the concave water collecting part has a first sinking part 332, a second sinking part 333 and a connecting wall 334, wherein the first sinking part 332 is an annular structure, the second sinking part 333 is arranged in the middle of the annular structure and is lower than the first sinking part 332, and the first sinking part 332 and the second sinking part 333 are connected by the connecting wall 334. The inner cover 20 also includes a cold air exhaust structure 23 penetrating the cover body 21, and the sealing turntable 30 also includes a push rod 36 sealingly penetrating the first sinking part 332, and the push rod 36 is located above the cold air exhaust structure 23. Specifically, before the pressure inside the cooking utensil is raised, the cold air in the cooking cavity can be discharged through the cold air exhaust structure 23. When the pressure in the cooking cavity rises to a certain level, the cold air exhaust structure 23 floats up under the pressure in the cooking cavity. After the cooking is finished and the pressure in the cooking cavity drops, the cold air exhaust structure 23 generally falls down under the action of its own gravity. However, in actual use, it is often difficult for the cold air exhaust structure 23 to fall down, thereby affecting the rotation of the inner cover 20 to the cover opening position. A push rod 36 is provided on the first sinking part 332. The user can press the push rod 36 downward so that the push rod 36 presses down the cold air exhaust structure 23 to open the cover smoothly. A avoidance part 322 is provided on the support turntable 32 at a position corresponding to the push rod 36. The push rod 36 is inserted into the avoidance part 322. The avoidance part 322 can be a concave structure or a avoidance opening structure, so that the push rod 36 and the first sinking part 332 connected to the push rod 36 can have a certain downward movement ability.

[0076] A second sinking portion 333 is provided that is lower than the first sinking portion 332, so that dirt such as condensed water and food residues are first gathered in the space formed by the second sinking portion 333 and the connecting wall 334, thereby preventing dirt such as condensed water and food residues from remaining above the push rod 36 and affecting the user's experience.

[0077] The exhaust pipe 221 of the exhaust structure 22 is passed through the second sinking portion 333 , and the pressure limiting valve 222 is located above the second sinking portion 333 , so that the upper part of the exhaust structure 22 can be sunk into the range of the sealing turntable 30 as much as possible to avoid protruding upward from the surface cover 12 .

[0078] Specifically, in this embodiment, the shape of the concave water collecting portion (specifically, the outer contour shape of the first sinking portion 332) is adapted to the shape of the mounting opening 121 provided on the face cover 12, and the shape of the sealing convex rib 11 (specifically, the first annular rib 111) is adapted to the shape of the mounting opening 121. When the inner cover 20 is located at the closed position and the sealing rotary disk 30 is located at the closed sealing position ( Figure 2The concave water collecting portion is directly opposite to the installation opening 121, so that the top area of ​​the sealing convex ring 331 located inside the sealing convex rib 11 is small, thereby preventing condensed water and food residues from remaining on the top surface of the sealing convex ring 331. Figure 3 As shown in the position, the concave water collecting portion is staggered with the installation opening 121, and a portion of the top surface of the sealing convex ring 331 is exposed at the installation opening 121.

[0079] like Figure 6 As shown, the thickness of the second sinking portion 333 is between 0.3 mm and 1 mm, so that the second sinking portion 333 has a large deformation capacity to adapt to the up and down floating of the exhaust structure 22. Preferably, the thickness of the second sinking portion 333 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0080] like Figure 6 As shown, the thickness of the connecting wall 334 is between 0.5 mm and 2 mm; a large amount of steam is generated during cooking, which results in a large amount of condensed water. The user can clean the condensed water and food residues collected in the concave water collection part by himself. The thickness of the connecting wall 334 is within the above range, so that it has a certain strength to prevent the sealing sheet 33 from being taken out when the user cleans. Preferably, the thickness of the connecting wall 334 can be 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0081] like Fig.13 As shown, the sealing turntable 30 includes a supporting turntable 32, an annular pressure plate 34 and a sealing sheet 33. The supporting turntable 32 is supported below the sealing sheet 33, and the sealing sheet 33 is sandwiched between the annular pressure plate 34 and the supporting turntable 32. The supporting turntable 32 and the annular pressure plate 34 are hard structures, and the sealing sheet 33 is a flexible structure. The sealing sheet 33 is positioned and fixed by clamping the sealing sheet 33 by the supporting turntable 32 and the annular pressure plate 34, so that the overall structure of the sealing turntable 30 is stable, and the installation and positioning of the sealing turntable 30 is convenient.

[0082] In this embodiment, the annular pressure plate 34, the sealing sheet 33 and the supporting turntable 32 are arranged in sequence from top to bottom. Of course, in an embodiment not shown in the figure, the annular pressure plate can also be arranged below the supporting turntable. Specifically, a slot structure with an inward opening can be arranged at the lower end of the sealing sheet, so that the outer edge of the supporting turntable is inserted into the slot structure, and the lower wall surface of the slot structure is pressed onto the supporting turntable by the annular pressure plate arranged below the supporting turntable, so as to fix the sealing sheet.

[0083] like Fig.12 and Fig.13As shown, the sealing turntable 30 also includes a positioning column 341 which is arranged on the annular pressure plate 34 and passes through the supporting turntable 32 and the sealing sheet 33. Before fixing the sealing turntable 30, the positioning column 341 can be used to first realize the positioning of the supporting turntable 32, the annular pressure plate 34 and the sealing sheet 33 to simplify the subsequent fixing operation.

[0084] Specifically, Fig.12 and Fig.13 As shown, the sealing sheet 33 also includes a connecting edge arranged on the outer periphery of the sealing convex ring 331, the connecting edge is clamped between the annular pressure plate 34 and the supporting turntable 32, the positioning column 341 is arranged on the lower surface of the annular pressure plate 34, a first connecting hole is arranged on the connecting edge, and a second connecting hole is arranged on the supporting turntable 32, the positioning column 341 passes through the first connecting hole and the second connecting hole in sequence to position the supporting turntable 32, the annular pressure plate 34 and the sealing sheet 33.

[0085] like Fig.11 and Fig.12 As shown, the sealing turntable 30 also includes a fastener 35 that penetrates the supporting turntable 32, the sealing sheet 33 and the annular pressure plate 34. The fastener 35 fixes the supporting turntable 32, the annular pressure plate 34 and the sealing sheet 33 to ensure the stability of the overall structure of the sealing turntable 30.

[0086] like Fig.14 and Fig.15 As shown, the sealing convex rib 11 includes a first annular rib 111 and a second annular rib 112. When the sealing rotary disk 30 is located at the closed sealing position, the first annular rib 111 is abutted against the sealing convex ring 331, and when the sealing rotary disk 30 is located at the open sealing position, the second annular rib 112 is abutted against the sealing convex ring 331. By providing the first annular rib 111 and the second annular rib 112, the sealing effect between the sealing rotary disk 30 and the upper cover 10 can be ensured in the closed sealing position and the open sealing position.

[0087] like Fig.14 and Fig.15 As shown, the sealing rib 11 includes a first rib body 113, a second rib body 114 and a third rib body 115. The first rib body 113 and the second rib body 114 are arranged to form a first annular rib 111. The third rib body 115 is located outside the second rib body 114 and is arranged to form a second annular rib 112 with the first rib body 113. That is, the first annular rib 111 and the second annular rib 112 share the first rib body 113, so that the structure of the sealing rib 11 is simple.

[0088] Specifically, the sealing turntable 30 rotates from the cover-closing sealing position to the cover-opening sealing position along the direction from the first rib 113 to the third rib 115 , that is, the third rib 115 is arranged on one side of the rotation direction of the sealing turntable 30 .

[0089] Correspondingly, in order to reduce the space occupied by the sealing turntable 30 inside the cover body assembly and leave exit space for setting up other structures, the top surface of the sealing convex ring 331 that cooperates with the first rib 113 can be set to be wider, and the top surface of the sealing convex ring 331 that cooperates with the second rib 114 and the third rib 115 can be set to be narrower. Specifically, the top surface of the sealing convex ring 331 includes a first sealing area and a second sealing area, the width of the first sealing area is smaller than the width of the second sealing area, the first sealing area is set corresponding to the second rib 114 and the third rib 115, and the second sealing area is set corresponding to the first rib 113.

[0090] Since the top surface of the sealing convex ring 331 abuts against the sealing rib 11, the sealing convex ring 331 will be worn. In order to reduce the wear of the sealing convex ring 331, the top surface of the sealing convex ring 331 can be polished and / or oil-sprayed to extend the service life of the sealing turntable 30.

[0091] Specifically, in this embodiment, the first annular rib 111 and the second annular rib 112 are both interference fit with the sealing convex ring 331, and the interference is between 0.3 mm and 1 mm. By making the first annular rib 111 and the second annular rib 112 both interference fit with the sealing convex ring 331, the sealing effect is ensured. Preferably, the interference between the first annular rib 111 and the sealing convex ring 331 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm; the interference between the second annular rib 112 and the sealing convex ring 331 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0092] like Figure 5 As shown, the sealing convex ring 331 is spaced apart from the supporting turntable 32. The sealing convex ring 331 is spaced apart from the supporting turntable 32, so that the sealing convex ring 331 has a certain ability to deform downward, and can compensate for the processing and installation errors of the upper cover 10 and the sealing turntable 30, thereby ensuring the sealing effect between the sealing turntable 30 and the upper cover 10.

[0093] Furthermore, in order to ensure the elastic deformation ability and structural strength of the sealing convex ring 331 so that the sealing convex ring 331 can always be sealed with the upper cover 10, a support rib that cooperates with the support turntable can be provided below the sealing convex ring.

[0094] like Figure 5 and Fig.13 As shown, the support turntable 32 is provided with a support rib 321, which extends below the sealing convex ring 331. The support rib 321 can position the sealing convex ring 331 in the lateral direction, so that the sealing convex ring 331 is kept in a position to abut against the sealing rib 11.

[0095] Specifically, there can be multiple (two or more) supporting ribs 321, and multiple supporting ribs 321 are nested. Since the sealing convex ring 331 has a certain width, the supporting ribs 321 also need to cover a sufficient area to ensure the positioning effect of the sealing convex ring 331. By providing multiple supporting ribs 321, the positioning effect of the sealing convex ring 331 can be ensured, and at the same time, the shrinkage phenomenon caused by the excessive width of a single supporting rib 321 can be avoided. Fig.13 As shown, in this embodiment, two supporting ribs 321 are provided, and a plurality of connecting ribs are provided between the two supporting ribs 321 .

[0096] Among them, Figure 5 As shown, the thickness of the top wall of the sealing protrusion ring 331 is between 1.5 mm and 3.5 mm; the thickness of the top wall of the sealing protrusion ring 331 within this range can take into account the deformation ability and structural strength of the sealing protrusion ring 331, so that the sealing protrusion ring 331 can always be sealed with the sealing rib 11. In addition, since the sealing protrusion ring 331 will move relative to the sealing rib 11, the sealing protrusion ring 331 will produce a certain degree of wear, and setting the sealing protrusion ring 331 to be thicker can ensure the service life of the sealing rotary disk 30. Preferably, the thickness of the top wall of the sealing protrusion ring 331 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm or 3.5 mm.

[0097] like Figure 5 As shown, the distance between the lower surface of the top wall of the sealing protruding ring 331 and the upper surface of the supporting convex rib 321 is between 0.5 mm and 2.5 mm. The distance between the lower surface of the top wall of the sealing protruding ring 331 and the upper surface of the supporting convex rib 321 within this range can take into account both the deformation ability and the structural strength of the sealing protruding ring 331, so that the sealing protruding ring 331 can always be sealed with the sealing convex rib 11. Preferably, the distance can be 0.5 mm, 1 mm, 1.5 mm, 2 mm or 2.5 mm.

[0098] Fig.17 A schematic structural diagram of the sealing turntable 30 according to the second embodiment of the cover assembly of the present invention is shown. The parts of the second embodiment of the cover assembly of the present application that are different from the first embodiment are described below in conjunction with the accompanying drawings, and the same contents in the two embodiments are not repeated here.

[0099] Specifically, the structural composition of the sealing turntable 30 in this embodiment is different from that in the first embodiment. In the first embodiment, the sealing turntable 30 has a three-layer structure; in this embodiment, the sealing turntable 30 has a two-layer structure.

[0100] like Fig.17As shown, the sealing turntable 30 includes a supporting turntable 32 and a sealing sheet 33 disposed on the supporting turntable 32. A mounting hole is disposed on the supporting turntable 32. A connecting column 335 penetrating the mounting hole is disposed below the sealing sheet 33. The connecting column 335 includes a column body and a stopper disposed at the lower end of the column body and cooperating with the lower surface of the supporting turntable 32. Specifically, by disposing the connecting column 335 below the sealing sheet 33 to achieve connection with the supporting turntable 32, fasteners such as screws can be omitted, thereby simplifying the structure of the sealing turntable 30.

[0101] like Fig.17 As shown, the cross-sectional size of the block gradually decreases from top to bottom, and the size of the upper end surface of the block is larger than the size of the mounting hole. When assembling the sealing sheet 33 and the supporting turntable 32, the lower end of the block is aligned with the mounting hole, and the block is squeezed and deformed to pass through the mounting hole and then cooperate with the stopper on the lower surface of the supporting turntable 32.

[0102] The setting of the stopper prevents the sealing sheet 33 from being brought out when the user cleans the condensed water and dirt inside the sealing rotary disk 30 .

[0103] like Fig.17 As shown, the sealing sheet 33 has a sealing convex ring 331 and a concave water collecting portion 336 located inside the sealing convex ring 331 , and the exhaust structure 22 is disposed through the concave water collecting portion 336 .

[0104] The present application also provides a cooking utensil, and an embodiment of the cooking utensil of the present application includes a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem in the related art that the eccentric setting of the pressure limiting valve makes it easy for water vapor to enter between the upper cover and the inner cover, and the cooking utensil with the above-mentioned cover assembly also has the above-mentioned advantages.

[0105] Specifically, in the present embodiment, the cooking utensil is a pressure cooking utensil. Of course, in embodiments not shown in the figure, the cooking utensil can also be products such as an electric rice cooker, a low-pressure rice cooker, a soybean milk machine, a food processor, a cooking machine, an electric stew pot, a multi-function pot, etc.

[0106] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0107] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0108] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
