[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 12 , Figure 13 , Figure 18 , Figure 19 , Figure 20 and Figure 21As shown, the embodiment of the utility model provides a cover assembly, which includes an outer cover 10 and an inner cover 20. The outer cover 10 includes a first top plate 11 and a first side plate 12 arranged around the edge of the first top plate 11 and extending downward. The inner cover 20 is detachably and rotatably arranged below the outer cover 10. The inner cover 20 includes a second top plate 21 and a second side plate 22 arranged around the edge of the second top plate 21 and extending downward. A plug-in matching structure 30 and a snap-in matching structure 40 are arranged at intervals between the first side plate 12 and the second side plate 22. The plug-in matching structure 30 includes a first slide groove 31 and an insert block 32 that can slidably match with the first slide groove 31. The snap-in matching structure 40 includes a second slide groove 41 and an insert block 32 that can slidably match with the second slide groove The slot 41 can slide with the card block 42, the second slot 41 is arranged on the first side plate 12 or the second side plate 22, the snap-fitting structure 40 also includes a slot 43, the slot 43 passes through the lower wall surface of the second slot 41 and the bottom surface of the first side plate 12 or the second side plate 22, the snap-fitting structure 40 also includes a supporting member 44 arranged in the slot 43, the supporting member 44 is movably arranged, and has an avoidance position to avoid the card block 42 from entering the second slot 41 and a supporting card block 42 so that the card block 42 remains in the supporting position in the second slot 41, wherein an anti-fool structure is arranged between the outer cover 10 and the inner cover 20, so that the insert block 32 is inserted into the first slot 31 and the card block 42 is inserted into the second slot 41.

[0048] When the cover assembly provided by the present embodiment is used, the inner cover 20 is installed below the outer cover 10. First, the inner cover 20 is placed below the outer cover 10, and then the entire inner cover 20 is tilted relative to the outer cover 10, and the plug block 32 is inserted into the first slide groove 31. At this time, the plug-in matching structure 30 is used as a reference to swing toward the outer cover 10, and the supporting member 44 is in the avoidance position. The block 42 enters the second slide groove 41 from the slot 43, so that the inner cover 20 and the outer cover 10 are arranged nearly parallel. When the supporting member 44 is in the supporting position, the block 42 remains in the second slide groove 41, so that the inner cover 20 is installed below the outer cover 10. On the contrary, the inner cover 20 can be removed from the bottom of the outer cover 10. When the inner cover 20 is installed below the outer cover 10, the inner cover 20 rotates below the outer cover 10, and the insert block 32 rotates in the first slide groove 31 and is supported and guided by the first slide groove 31, and the clamp block 42 rotates in the second slide groove 41 and is supported and guided by the second slide groove 41, so that the cover assembly can be closed in place. In addition, a fool-proof structure is provided between the outer cover 10 and the inner cover 20, which can ensure that the insert block 32 is inserted into the first slide groove 31 and the clamp block 42 is inserted into the second slide groove 41, so as to prevent the user from inserting the insert block 32 into the second slide groove 41 and the clamp block 42 into the first slide groove 31 when the inner cover 20 is assembled on the outer cover 10, resulting in the inner cover 20 being installed upside down, thereby ensuring that the inner cover 20 assembled on the outer cover 10 can play a pressure-bearing role. Therefore, the outer cover 10 of the present application does not need to be provided with a pivot, and the inner cover 20 can be installed below the outer cover 10, and the pivot hole matched with the pivot is omitted on the inner cover 20, so that the inner cover 20 does not need to be aligned with the pivot for installation, which reduces the difficulty of assembly. In addition, the present application installs the inner cover 20 below the outer cover 10 by inserting the insert block 32 into the first slide groove 31 and the clamp block 42 slides into the second slide groove 41, which is easier to assemble, and the foolproof structure can ensure that the insert block 32 is inserted into the second slide groove 41 and the clamp block 42 is inserted into the first slide groove 31. Therefore, the technical solution of the present application effectively solves the problem in the related art that the pivot hole on the inner cover 20 needs to be aligned with the pivot for installation, which makes assembly difficult.

[0049] Among them, a plug-in fitting structure 30 and a snap-in fitting structure 40 are arranged at intervals between the first side panel 12 and the second side panel 22, including: the plug-in fitting structure 30 can be directly arranged between the first side panel 12 and the second side panel 22, or the snap-in fitting structure 40 can be indirectly arranged between the first side panel 12 and the second side panel 22.

[0050] Specifically, the second slide groove 41 is provided on the second side plate 22, and the snap-fit ​​structure 40 further includes a slot 43, which passes through the lower wall surface of the second slide groove 41 and the bottom surface of the second side plate 22. In this embodiment, in order to stably install the inner cover 20 under the outer cover 10, the clamping block 42 and the inserting block 32 are respectively located on both sides of the inner cover 20.

[0051] It should be noted that the anti-fooling structure includes various implementation manners:

[0052] (1) The size of the insertion block 32 is larger than that of the clamping block 42, that is, the circumferential size of the insertion block 32 is larger than the circumferential size of the clamping block 42. The clamping block 42 can extend into the second sliding groove 41 through the notch 43. Since the size of the insertion block 32 is larger than that of the clamping block 42, the insertion block 32 cannot be inserted into the second sliding groove 41 through the notch 43, thereby preventing the inner cover 20 from being misassembled;

[0053] (2) The thickness dimension of the insertion block 32 is larger than the thickness dimension of the second sliding groove 41. In this way, the insertion block 32 cannot be inserted into the second sliding groove 41, so that the inner cover 20 cannot rotate, thereby playing an anti-fooling role and preventing the inner cover 20 from being installed in the reverse direction;

[0054] (3) The thickness dimension of the clamping block 42 is larger than the thickness dimension of the first sliding groove 31. Furthermore, the clamping block 42 can be prevented from being inserted into the first sliding groove 31. By limiting with the thickness dimension of the clamping block 42 and the first sliding groove 31, the installation of the inner cover 20 can be prevented from being installed in the reverse direction;

[0055] (4) Other anti-fooling structures are provided on the first sliding groove 31, the second sliding groove 41 or the notch 43, such as a limiting boss or a limiting groove. Corresponding limiting grooves or limiting bosses are provided on the clamping block 42 and the insertion block 32 for matching installation, thereby playing an anti-fooling role.

[0056] Such as Figure 2 、 Figure 5 and Figure 6 As shown, in the circumferential direction of the cover assembly, the size of the clamping block 42 is smaller than the size of the notch 43 and the size of the notch 43 is smaller than the size of the insertion block 32 to form an anti-fooling structure. With the above structure, the size of the clamping block 42 is smaller than the size of the notch 43, which is convenient for distinguishing the insertion block 32 and the clamping block 42. Furthermore, the clamping block 42 can extend into the notch 43 and then can rotate in the second sliding groove 41. And, since the size of the notch 43 is smaller than the size of the insertion block 32, the insertion block 32 can be prevented from being inserted into the notch 43, thereby playing a role in preventing the inner cover 20 from being installed in the reverse direction. Therefore, by limiting the circumferential dimensions of the insertion block 32, the clamping block 42 and the notch 43, so that the insertion block 32 can only be inserted into the first sliding groove 31 and cannot be inserted into the second sliding groove 41, the inner cover 20 can be anti-fooled.

[0057] In this embodiment, in the vertical direction of the cover assembly, the size of the insertion block 32 is larger than that of the second sliding groove 41 to form an anti-misassembly structure. With the above structure, by making the size of the insertion block 32 larger than that of the second sliding groove 41, that is, the thickness dimension of the insertion block 32 is larger than the thickness dimension of the second sliding groove 41, it can be avoided that the insertion block 32 is directly inserted into the second sliding groove 41, preventing the clamping block 42 and the insertion block 32 from being misassembled vertically. Furthermore, it can ensure that the clamping block 42 is inserted into the second sliding groove 41 and the insertion block 32 is inserted into the first sliding groove 31, correctly installing the inner cover 20 on the outer cover 10.

[0058] As Figure 2 shown, in the vertical direction of the cover assembly, the size of the first sliding groove 31 is larger than that of the insertion block 32, and the size of the second sliding groove 41 is larger than that of the clamping block 42. In this way, the size of the first sliding groove 31 is larger than that of the insertion block 32, and the size of the second sliding groove 41 is larger than that of the clamping block 42. The insertion block 32 has a floating space in the first sliding groove 31, and the clamping block 42 also has a floating space in the second sliding groove 41, facilitating the inner cover 20 to float a certain distance relative to the outer cover 10 after being subjected to the pressure inside the cooking appliance, meeting the upper pressure requirement of the cooking appliance.

[0059] As Figures 12 to 14 shown, in the vertical direction of the cover assembly, there is a first difference H1 between the size of the first sliding groove 31 and the size of the insertion block 32, and there is a second difference H2 between the size of the second sliding groove 41 and the size of the clamping block 42. Both the first difference H1 and the second difference H2 are in the range of 2 mm to 6 mm. Setting the first difference H1 and the second difference H2 within the above range enables the insertion block 32 to have a sufficiently large floating space in the first sliding groove 31, and the clamping block 42 also has a sufficiently large floating space in the second sliding groove 41, facilitating the inner cover 20 to float a certain distance relative to the outer cover 10 after being subjected to the pressure inside the cooking appliance, meeting the upper pressure requirement of the cooking appliance.

[0060] It should be noted that both the first difference H1 and the second difference H2 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, and any other value between 2 mm and 6 mm.

[0061] In this embodiment, in the circumferential direction of the cover assembly, there is a first ratio between the size of the first sliding groove 31 and the size of the insertion block 32, and there is a second ratio between the size of the second sliding groove 41 and the size of the clamping block 42. Both the first ratio and the second ratio are between 3 and 5. Setting the first ratio and the second ratio within the above range can ensure that when the insertion block 32 is inserted into the first sliding groove 31 and the clamping block 42 is inserted into the second sliding groove 41, the inner cover 20 can rotate, and furthermore, the side wall of the first sliding groove 31 can support and guide the insertion block 32, and the side wall of the second sliding groove 41 can support and guide the clamping block 42.

[0062] It should be noted that the first ratio and the second ratio can both be 3, 3.5, 4, 4.5, 5, and any other value between 4 and 5.

[0063] like Figure 5 , Figure 6 as well as Figure 15 As shown, the inner cover 20 includes a pressure-bearing cover 23 and a fixed cover 24 arranged on the pressure-bearing cover 23, the pressure-bearing cover 23 includes a second top plate 21 and a second side plate 22, and the plug block 32 and the clamp block 42 are both arranged on the outer side wall of the fixed cover 24. With the inner cover 20 of the above structure, the fixed cover 24 is arranged on the pressure-bearing cover 23, the pressure-bearing cover 23 plays a role of bearing pressure, and the plug block 32 and the clamp block 42 are both arranged on the outer side wall of the fixed cover 24, so that the fixed cover 24 is easy to produce and process, and the plug block 32 and the clamp block 42 cannot be arranged on the pressure-bearing cover 23, thereby reducing production costs.

[0064] like Figures 10 to 17 As shown, the second chute 41 is arranged on the first side plate 12, the block 42 is arranged on the second side plate 22, and the supporting member 44 includes a supporting hook that is movably or swingably arranged on the first side plate 12, and the supporting hook includes a hook surface arranged toward the inside of the slot 43, and when the hook surface is flush with the lower wall surface of the second chute 41, the supporting member 44 is in a supporting position. In the process of the block 42 entering the second chute 41, the block 42 slides into the slot 43 and can squeeze the supporting hook, at this time, the supporting member 44 moves from the supporting position to the avoidance position, and when the block 42 passes through the slot 43 and then enters the second chute 41, the supporting member 44 can move from the avoidance position to the supporting position, at this time, on the one hand, the hook surface of the supporting member 44 is flush with the lower wall surface of the second chute 41 and can block the slot 43, preventing the supporting member 44 from passing through the slot 43 and leaving the second chute 41. On the other hand, the support member 44 supports the block 42 so that the block 42 is kept in the second slide groove 41. In this way, the support hook is provided to facilitate the support member 44 to move between the avoidance position and the support position. When the block 42 rotates in the second slide groove 41, the block 42 can smoothly transition from the hook surface of the support member 44 to the lower wall surface of the second slide groove 41, and in the opposite direction, it can smoothly transition from the lower wall surface of the second slide groove 41 to the hook surface of the support member 44.

[0065] like Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 18 , Figure 19 , Figure 20 as well as Figure 21As shown, a stopper 51 is provided on the inner wall of the outer cover 10, a supporting surface 25 and an avoiding concave surface 26 are provided on the outer wall of the inner cover 20, pot teeth are provided on the pot body of the cooking utensil, and a cover tooth 221 capable of cooperating with the pot teeth is provided on the lower edge of the second side plate 22. When the inner cover 20 is installed on the outer cover 10 and the cover tooth 221 is separated from the pot teeth, the supporting surface 25 cooperates with the stopper 51 to stop, and when the inner cover 20 is rotated under the outer cover 10 so that the cover tooth 221 and the pot teeth are buckled together, the avoiding concave surface 26 cooperates with the stopper 51 to avoid. At this time, the insert block 32 is inserted into the first slide groove 31 and abuts against the lower wall of the first slide groove 31, so that the inner cover 20 is restricted between the stopper 51 and the lower wall, thereby limiting the tilting range of the inner cover 20. When the inner cover 20 is straightened so that the block 42 enters the second slide groove 41, the inner cover 20 is approximately installed horizontally below the outer cover 10. When the inner cover 20 rotates below the outer cover 10, due to the stopper cooperation of the support surface 25 and the stopper 51, and the insert block 32 is supported and guided by the first slide groove 31, the block 42 is supported and guided by the second slide groove 41, so that the inner cover 20 can rotate in the horizontal plane, preventing tilting and shaking, and preventing the subsequent cover teeth 221 and the pot teeth from being locked together. When the cover teeth 221 and the pot teeth are locked together, the avoidance concave surface 26 and the stopper 51 are avoided. In this case, when the cooking utensil is pressed upward, the pressure inside the cooking utensil will push the inner cover 20 to float upward relative to the outer cover 10. The avoidance matching relationship between the avoidance concave surface 26 and the stopper 51 can prevent the stopper 51 from interfering with the inner cover 20, so that the inner cover 20 can float upward smoothly. The stopper 51 is preferably a stop rib.

[0066] like Figure 2 and Figure 3 As shown, the exhaust pipe 13 is arranged on the first top plate 11, and the avoidance hole 211 for avoiding the exhaust pipe 13 is arranged on the second top plate 21. In this way, the avoidance hole 211 only avoids the exhaust pipe 13. Since the pivot in the related art is not arranged on the first top plate 11, the avoidance hole 211 does not need to be arranged as a pivot hole that cooperates with the pivot, which reduces the number of components and reduces the cost. In addition, the exhaust pipe 13 arranged on the first top plate 11 will not interfere with the pivot in the related art, and there is no need to adjust the original setting position of the exhaust pipe 13 on the first top plate 11, which ensures the original layout design on the first top plate 11, that is, the cover assembly of the present application only makes structural improvements within a small range, and the exhaust pipe 13 can be kept in the original position. In this way, during the mold processing of the outer cover 10 and the inner cover 20, there is no need to make major adjustments to the mold, which can reduce the design cost and improve the processing efficiency.
