In this way, since the pivot hole on the inner cover is aligned with the pivot for installation, assembly is difficult. Summary of the invention

[0005] The main purpose of the present invention is to provide a cover assembly and a cooking utensil having the same, so as to solve the problem in the related art that the pivot hole on the inner cover needs to be aligned with the pivot for installation, making assembly difficult.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a cover assembly is provided, comprising: an outer cover, comprising a first top plate and a first side plate arranged around the edge of the first top plate and extending downward; an inner cover, which is detachably and rotatably arranged below the outer cover, and the inner cover comprises a second top plate and a second side plate arranged around the edge of the second top plate and extending downward, a plug-in matching structure and a snap-in matching structure are arranged at intervals between the first side plate and the second side plate; the plug-in matching structure comprises a first slide groove and an insert block that can slidably match with the first slide groove; the snap-in matching structure comprises a second slide groove and an insert block that can slidably match with the second The slide groove can slide with the card block, the second slide groove is arranged on the first side plate or the second side plate, the snap-fit ​​structure also includes a slot connected to the second slide groove, the slot extends downward from the second slide groove to the bottom of the outer cover or the inner cover, and the snap-fit ​​structure also includes a supporting member arranged in the slot, the supporting member can be movably arranged, and has an avoidance position to avoid the card block from entering the second slide groove and a supporting card block to keep the card block in a supporting position in the second slide groove; wherein, in the up and down direction of the cover body assembly, the size of the first slide groove is larger than the size of the plug, and the size of the second slide groove is larger than the size of the card block.

[0007] According to the technical solution of the present invention, during the process of installing the inner cover below the outer cover, the inner cover is first placed below the outer cover, and then the entire inner cover is tilted relative to the outer cover, and the plug block is inserted into the first slide groove. At this time, the plug-in matching structure is used as a reference to swing toward the outer cover, the supporting member is in the avoidance position, and the card block enters the second slide groove from the slot, so that the inner cover and the outer cover are arranged nearly parallel. When the supporting member is in the supporting position, the card block is kept in the second slide groove to install the inner cover below the outer cover. On the contrary, the inner cover can be removed from the bottom of the outer cover. When the inner cover is installed below the outer cover, the inner cover rotates below the outer cover, and at this time, the plug block rotates in the first slide groove and is supported and guided by the first slide groove, and the card block rotates in the second slide groove and is supported and guided by the second slide groove, so that the cover assembly is covered in place. After the cover assembly is covered in place, since the size of the first slide groove is larger than the size of the plug block, and the size of the second slide groove is larger than the size of the card block in the up and down direction of the cover assembly. The insert block has floating space in the first slide groove, and the card block also has floating space in the second slide groove, so that after the inner cover is subjected to the pressure in the cooking utensil, the inner cover floats a certain distance relative to the outer cover to meet the upward pressure requirement of the cooking utensil. In this way, the inner cover of the present application can be installed below the outer cover without setting a pivot on the outer cover, and the pivot hole that matches the pivot is omitted on the inner cover, so that the inner cover does not need to be aligned with the pivot for installation, which reduces the difficulty of assembly. Moreover, the present application inserts the insert block into the first slide groove, and the card block slides into the second slide groove to realize the installation of the inner cover below the outer cover, which is easier to assemble. Therefore, the technical solution of the present application effectively solves the problem in the related art that the pivot hole on the inner cover needs to be aligned with the pivot for installation, making assembly difficult.

[0008] Furthermore, in the vertical direction of the cover assembly, there is a first difference between the size of the first chute and the size of the plug-in block, and there is a second difference between the size of the second chute and the size of the clamping block, and the first difference and the second difference are both within the range of 0.5 mm to 6 mm. The first difference and the second difference are both within the range of 0.5 mm to 6 mm, so that the plug-in block has a sufficiently large floating space in the first chute, and the clamping block also has a sufficiently large floating space in the second chute, so that after the inner cover is subjected to the pressure in the cooking utensil, the inner cover floats a certain distance relative to the outer cover, meeting the upward pressure requirement of the cooking utensil.

[0009] Furthermore, the inner cover is circular, and in the circumferential direction of the inner cover, the size of the plug block is larger than that of the card block. In the above structure, since the size of the plug block is larger than that of the card block, it is convenient to distinguish the plug block from the card block, so that the plug block can only be inserted into the first slide groove, but not into the second slide groove, which plays a fool-proof role. And / or, in the up and down direction of the cover body assembly, the lower surface of the plug block slide groove protrudes downward from the lower surface of the card block slide groove. In this way, there is a height difference between the lower surface of the card block slide groove and the lower surface of the plug block slide groove. On the one hand, when the inner cover is installed on the outer cover, when the supporting member is in the supporting position, the supporting member is supported below the lower surface of the card block slide groove, and the card block slide groove is padded, so that the inner cover is located below the outer cover in a relatively horizontal state, and it is also convenient for the lower groove wall of the second slide groove to support the card block, thereby facilitating the smooth rotation of the inner cover. On the other hand, the thickness of the plug block slide groove is thicker than that of the card block slide groove, and the plug block slide groove can improve the structural strength of the inner cover. Furthermore, the first top plate is provided with an exhaust pipe, and the second top plate is provided with a evacuation hole for evading the exhaust pipe. The evacuation hole is only used to evade the exhaust pipe, and since the first top plate is not provided with a pivot in the related art, the evacuation hole does not need to be provided as a pivot hole that cooperates with the pivot, thereby reducing components and reducing costs.

[0010] Further, the second slide groove is arranged on the first side plate, the clamping block is arranged on the second side plate, and the supporting member includes a supporting hook or a pull button, wherein the supporting hook is movably arranged on the first side plate, and the pull button is swingably arranged on the first side plate. The arrangement of the supporting hook or the pull button facilitates the supporting member to move between the avoidance position and the supporting position.

[0011] Furthermore, the supporting hook or the lever includes a supporting surface arranged toward the inside of the slot, and when the supporting surface is flush with the lower wall of the second slide slot, the supporting member is in the supporting position. In the above structure, when the block rotates in the second slide slot, the block can smoothly transition from the supporting surface of the supporting member to the lower wall of the second slide slot, and in the opposite direction, it can smoothly transition from the lower wall of the second slide slot to the supporting surface of the supporting member.

[0012] Furthermore, the cover assembly further includes a handle and a transmission member movably arranged on the outer cover, and a driving column penetrating the transmission member is arranged on the inner cover, and when the handle moves, the transmission member is driven to move, so as to drive the inner cover to rotate below the outer cover through the driving column. In the above structure, the user operates the handle to move, so as to drive the driving column by driving the movement of the transmission member, so as to drive the inner cover to rotate below the outer cover.

[0013] Furthermore, a stopper is provided on the inner wall of the outer cover, a supporting surface and an avoidance concave surface are provided on the outer wall of the inner cover, pot teeth are provided on the pot body of the cooking utensil, and a cover tooth capable of cooperating with the pot teeth is provided on the lower edge of the second side plate. When the inner cover is installed on the outer cover and the cover tooth and the pot tooth are separated, the supporting surface cooperates with the stopper, and when the inner cover rotates below the outer cover so that the cover tooth and the pot tooth are buckled together, the avoidance concave surface cooperates with the stopper. In the above structure, when the inner cover rotates below the outer cover, the supporting surface cooperates with the stopper, and the insert block is supported and guided by the first slide groove, and the clamp block is supported and guided by the second slide groove, so that the inner cover can rotate in a horizontal plane, preventing tilting and shaking, and preventing the subsequent cover tooth and the pot tooth from being stuck together.

[0014] Furthermore, the first slide groove includes an upper side wall and a lower side wall that are arranged opposite to each other, and the lower side wall is closer to the mouth of the outer cover than the upper side wall. The cover body assembly also includes a positioning piece, and the positioning piece is arranged at the upper side wall. When the inner cover is installed below the outer cover, the plug block is positioned and matched with the positioning piece, and the plug block is positioned between the positioning piece and the lower side wall. In the above structure, the plug block uses the positioning piece as a positioning reference, so that the inner cover can swing with this positioning reference to be installed on the outer cover, and the plug block is prevented from sliding in the first slide groove in the up and down direction, which reduces the difficulty of installation, so that the inner cover can be smoothly installed on the outer cover.

[0015] According to another aspect of the present invention, a cooking utensil is provided, comprising a pot body and a cover assembly disposed on the pot body, wherein the cover assembly is the above-mentioned cover assembly.

[0016] Furthermore, the pot body includes a heat-insulating cover and an inner pot arranged in the heat-insulating cover, the heat-insulating cover is provided with pot teeth, and the lower edge of the second side plate is provided with cover teeth. When the supporting member is in the avoidance position, the clamping block slides from the notch into the second slide groove, and the cover teeth and the pot teeth are separated; when the clamping block rotates in the second slide groove, the cover teeth and the pot teeth are buckled together.

Therefore, other examples of exemplary embodiments may have different values. 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.

[0052] like Figures 1 to 8aAs shown, the present application provides a cover assembly, and an embodiment of the cover assembly 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 that is arranged around the edge of the first top plate 11 and extends downward. The inner cover 20 is detachably and rotatably arranged below the outer cover 10, and the inner cover 20 includes a second top plate 21 and a second side plate 22 that is arranged around the edge of the second top plate 21 and extends downward, and a plug-in mating structure 30 and a snap-in mating structure 40 are arranged at intervals between the first side plate 12 and the second side plate 22. The plug-in mating structure 30 includes a first slide groove 31 and an insert block 32 that can slidably fit with the first slide groove 31. The snap-fit ​​structure 40 includes a second slide groove 41 and a block 42 that can slide with the second slide groove 41. The second slide groove 41 is arranged on the first side plate 12. The snap-fit ​​structure 40 also includes a slot 43 that is connected to the second slide groove 41. The slot 43 runs downward from the second slide groove 41 to the bottom of the outer cover 10. The snap-fit ​​structure 40 also includes a supporting member 44 that is arranged in the slot 43. The supporting member 44 is movably arranged and has a avoiding position to avoid the block 42 from entering the second slide groove 41 and supports the block 42 so that the block 42 remains in the supporting position in the second slide groove 41. In the up-down direction of the cover assembly, the size of the first slide groove 31 is larger than the size of the insert block 32, and the size of the second slide groove 41 is larger than the size of the block 42.

[0053] In the process of installing the inner cover 20 below the outer cover 10 by applying the technical solution of this embodiment, the inner cover 20 is first 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, the supporting member 44 is in the avoidance position, and 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 below 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 plug 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 is closed in place. After the cover assembly is closed in place, since the size of the first slide groove 31 is larger than the size of the plug block 32, and the size of the second slide groove 41 is larger than the size of the clamp block 42 in the up and down direction of the cover assembly, the plug block 32 has a floating space in the first slide groove 31, and the clamp block 42 also has a floating space in the second slide groove 41, so that after the inner cover 20 is subjected to the pressure in the cooking utensil, the inner cover 20 floats a distance relative to the outer cover 10, meeting the upward pressure requirement of the cooking utensil. In this way, the outer cover 10 of this embodiment 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 provided on the inner cover 20 to match the pivot is omitted, so 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 inserts the insert block 32 into the first slide groove 31, and the clamp block 42 slides into the second slide groove 41 to achieve the installation of the inner cover 20 below the outer cover 10, which is easier to assemble. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the pivot hole on the inner cover needs to be aligned with the pivot for installation, making assembly difficult.

[0054] In other embodiments, the second slide groove 41 is disposed on the second side plate 22 , and the snap-fitting structure 40 further includes a slot 43 connected to the second slide groove 41 , and the slot 43 extends downward from the second slide groove 41 to the bottom of the inner cover 20 .

[0055] In this embodiment, the block 42 and the insert block 32 are respectively located on both sides of the inner cover 20. In addition, the insert block 32 and the block 42 balance and share the gravity of the inner cover 20, so that the inner cover rotates more smoothly, and the insert block 32 rotates smoothly in the first slide groove 31, and the block 42 rotates smoothly in the second slide groove 41.

[0056] like Figures 6 to 8aAs shown, in the vertical direction of the cover assembly, there is a first difference H1 between the size of the first chute 31 and the size of the plug 32, and there is a second difference H2 between the size of the second chute 41 and the size of the clamp 42, and the first difference H1 and the second difference H2 are both within the range of 0.5mm to 6mm. The first difference H1 and the second difference H2 are both within the range of 0.5mm to 6mm, so that the plug 32 has a sufficiently large floating space in the first chute 31, and the clamp 42 also has a sufficiently large floating space in the second chute 41, so that after the inner cover 20 is subjected to the pressure in the cooking utensil, the inner cover 20 floats a distance relative to the outer cover 10, meeting the upward pressure requirement of the cooking utensil.

[0057] The first difference H1 and the second difference H2 mentioned above are preferably both 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm or 6 mm.

[0058] like Figure 2 , Fig.10 and Fig.11 As shown, the inner cover 20 is circular, and the size of the insert block 32 is larger than the size of the clamp block 42 in the circumferential direction of the inner cover 20. In this way, on the one hand, since the size of the insert block 32 is larger than the clamp block 42, it is easy to distinguish the insert block 32 from the clamp block 42, so that the insert block 32 can only be inserted into the first slide groove 31, but not into the second slide groove 41, which plays a fool-proof role. On the other hand, since the size of the insert block 32 is larger than the clamp block 42, after the insert block 32 is first inserted into the first slide groove 31, it can form a stable reference, which is convenient for the inner cover 20 to swing toward the outer cover 10, and also convenient for the clamp block 42 to smoothly align with the slot 43, so as to enter the second slide groove 41.

[0059] In this embodiment, in the up and down directions of the inner cover 20, the size of the insert block 32 is larger than the size of the clamping block 42, so that the insert block 32 is thicker, and the insert block 32 can easily fit on the groove wall of the first slide groove 31 and can be easily aligned in the first slide groove 31 for easy assembly.

[0060] In the vertical direction of the cover assembly, the lower surface of the insert block 32 protrudes downward from the lower surface of the clamp block 42. In this way, there is a height difference between the lower surface of the clamp block 42 and the lower surface of the insert block 32. On the one hand, when the inner cover is installed on the outer cover, when the supporting member is in the supporting position, the supporting member is supported below the lower surface of the clamp block 42, and the clamp block 42 is padded, so that the inner cover is located below the outer cover in a relatively horizontal state, and it is also convenient for the lower groove wall of the second slide groove to support the clamp block 42, thereby facilitating the inner cover to rotate smoothly. On the other hand, the thickness of the insert block 32 is thicker than that of the clamp block 42, and the insert block 32 can improve the structural strength of the inner cover.

[0061] like Figure 2 and Fig.10As shown, the first top plate 11 is provided with an exhaust pipe 13, and the second top plate 21 is provided with an escape hole 211 for evading the exhaust pipe 13, and the escape hole 211 is preferably a circular hole. In this way, the escape hole 211 only escapes the exhaust pipe 13. Since the first top plate 11 is not provided with a pivot in the related art, the escape hole 211 does not need to be provided as a pivot hole that cooperates with the pivot, thereby reducing components and reducing costs. In addition, the exhaust pipe 13 provided 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, thereby ensuring 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 can keep the exhaust pipe 13 and the handle 51 (see below) 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 a large adjustment to the mold, which can reduce the design cost and improve the processing efficiency.

[0062] In this embodiment, a pressure limiting valve capable of blocking or opening the exhaust pipe 13 is provided above the exhaust pipe 13 .

[0063] like Figures 2 to 8a As shown, the second chute 41 is arranged on the first side plate 12, and the block 42 is arranged on the second side plate 22. In the first embodiment of the supporting member of the cover assembly, the supporting member 44 includes a supporting hook 441 movably arranged on the first side plate 12. 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 441. At this time, the supporting member 44 moves from the supporting position to the avoidance position. 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 supporting member 44 blocks the slot 43 to prevent the supporting member 44 from passing through the slot 43 and escaping from the second chute 41. On the other hand, the supporting member 44 supports the block 42 so that the block 42 remains in the second chute 41. In this way, the setting of the supporting hook 441 facilitates the supporting member 44 to move between the avoidance position and the supporting position. In the first embodiment of the supporting member of the cover assembly, in order to facilitate driving the supporting hook 441, the cover assembly also includes a button 45 movably arranged on the outer cover 10, and the button 45 is in contact with the supporting hook 441 through a driving inclined surface. When the user presses the button 45, the driving inclined surface drives the supporting hook 441 to move, so that the supporting member 44 moves from the supporting position to the avoidance position. The cover assembly also includes a first elastic member 46 arranged between the outer cover 10 and the supporting hook 441, and the first elastic member 46 applies an elastic force to the supporting hook 441 to keep the supporting member 44 in the supporting position. When the supporting hook 441 is no longer subjected to the pressing force applied by the button 45, the supporting hook 441 can automatically move toward the supporting position of the supporting member 44 under the action of the elastic force of the first elastic member 46, so that the supporting member 44 moves from the avoidance position to the supporting position.

[0064] Specifically, the moving direction of the button 45 is perpendicular to the moving direction of the supporting hook 441 .

[0065] Compared with the detachable inner cover for repairing the cover assembly in the conventional setting, the first embodiment of the supporting member controls the supporting member 44 to move to the supporting position relative to the outer cover 10 through the button 45, and the inner cover 20 can be placed on the supporting member 44, ensuring that the inner cover 20 is installed on the outer cover 10, and the supporting member 44 and the inner cover 20 are overlapped and matched, so that the inner cover 20 can be prevented from being separated from the outer cover 10, making the installation method convenient. When the inner cover 20 is removed from the outer cover 10, the supporting member 44 is controlled by the button 45 to move from the supporting position to the avoidance position, so that the inner cover 20 is easily removed from the outer cover 10, and one-button quick removal and easy removal are achieved, so that the user can clean the removed inner cover 20 and outer cover 10. With the cover body assembly adopting the above-mentioned structure, the supporting member 44 on the outer cover 10 can not only facilitate the disassembly and assembly of the inner cover 20 and the outer cover 10, but also when the inner cover 20 is placed on the supporting member 44, the supporting member 44 can support the inner cover 20, and the inner cover 20 can rotate relative to the supporting member 44, which guides the rotation of the inner cover 20, thereby improving the structural reliability and practicality of the cover body assembly.

[0066] like Figures 2 to 8a As shown, the supporting hook 441 includes a supporting surface arranged toward the inside of the slot 43, and when the supporting surface is flush with the lower wall surface 411 of the second slide slot 41, the supporting member 44 is in the supporting position. In this way, when the block 42 rotates in the second slide slot 41, the block 42 can smoothly transition from the supporting surface of the supporting member 44 to the lower wall surface 411 of the second slide slot 41, and can smoothly transition from the lower wall surface 411 of the second slide slot 41 to the supporting surface of the supporting member 44 in the opposite direction.

[0067] like Figures 2 to 7 and Figure 8bAs shown, in the second embodiment of the supporting member of the cover assembly, the supporting member 44 includes a pull button 442 that can be swingably arranged on the first side plate 12, and the user pulls the pull button 442 to swing the supporting member 44 between the avoidance position and the supporting position. The cover assembly also includes a second elastic member 47, and the pull button 442 is swingably arranged on the outer cover 10. When the supporting member 44 is in the supporting position, the inner cover 20 is placed on the pull button 442, and the second elastic member 47 is arranged between the pull button 442 and the outer cover 10, and applies an elastic force toward the inner cover 20 to the pull button 442. The supporting member 44 of the above structure is swingably arranged on the outer cover 10 by means of the pull button 442, and the second elastic member 47 is arranged between the pull button 442 and the outer cover 10, and then when the supporting member 44 is in the supporting position, under the action of the second elastic member 47, the inner cover 20 is ensured to be placed on the pull button 442, and when the inner cover 20 is disassembled, the pull button 442 is controlled to swing in a direction away from the inner cover 20, so that the pull button 442 overcomes the elastic force of the second elastic member 47, and then the inner cover 20 is ensured to be separated from the pull button 442, and then the pull button 442 is reset under the elastic force of the second elastic member 47, and the operation method is simple, and one-button quick disassembly and easy disassembly are realized. The pull button 442 includes a supporting surface arranged toward the inside of the slot 43.

[0068] like Figures 9 to 21 As shown, the cover assembly further includes a handle 51 and a transmission member 52 movably disposed on the outer cover 10. A driving column 212 penetrating the transmission member 52 is disposed on the inner cover 20. When the handle 51 moves, the transmission member 52 is driven to move, so as to drive the inner cover 20 to rotate below the outer cover 10 through the driving column 212. In this way, the user operates the handle 51 to move, so as to drive the driving column 212 by driving the movement of the transmission member 52, so as to drive the inner cover 20 to rotate below the outer cover 10.

[0069] It should be noted that, in this embodiment, the transmission member 52 is moved by the handle 51. In other embodiments, the transmission member 52 is moved by the drive motor, and a trigger switch is provided on the cooking utensil for turning on or off the drive motor.

[0070] In the present application, the transmission member 52 includes a slide plate or a swing rod. When the operating handle 51 moves, the handle 51 can drive the slide plate to move, so as to drive the driving column 212 to rotate. Or when the operating handle 51 moves, the handle 51 can drive the swing rod to swing on the horizontal plane, so as to drive the driving column 212 to rotate. In the present application, in the process of installing the inner cover 20 below the outer cover 10, it is necessary to first tilt the entire inner cover 20 relative to the outer cover 10, and then insert the insert block 32 into the first slide groove 31. After that, the inner cover 20 is easier to tilt. In order to facilitate installation, the inner cover 20 needs to be limited within a certain tilt range to achieve tilted installation.

[0071] like Figures 1 to 10 , Fig.21 and Fig. 22 As shown, the transmission member 52 has a first position and a second position. The lower edge of the inner cover 20 is provided with a cover tooth 23 that cooperates with the pot tooth of the pot body of the cooking utensil. When the transmission member 52 is in the first position, the inner cover 20 is in an unlocked state, and when the transmission member 52 is in the second position, the inner cover 20 is in a locked state. The cover assembly also includes an elastic push-up member 63 that is movably arranged on the outer cover 10. The elastic push-up member 63 has an initial position that limits the transmission member 52 to the first position and a avoidance position that avoids the transmission member 52 so that the transmission member 52 can move. When the inner cover 20 is installed below the outer cover 10, the inner cover 20 abuts and cooperates with the elastic push-up member 63, so that the elastic push-up member 63 moves from the initial position to the avoidance position, and the inner cover 20 can float up and down.

[0072] like Figures 1 to 10 , Fig.21 and Fig. 22As shown, when the user operates the handle 51 to move and drive the transmission member 52 to the first position, the inner cover 20 is in the unlocked state, and the inner cover 20 can be removed from the outer cover 10. Since the elastic push-up member 63 limits the transmission member 52 to the initial position of the first position, it is prevented that the user misoperates the handle 51 and changes the position of the transmission member 52, and effectively prevents the handle from being misoperated by the user. In the process of installing the inner cover 20 below the outer cover 10 again, the inner cover 20 can be smoothly installed below the outer cover 10. Moreover, in this process, the inner cover 20 is first tilted relative to the outer cover 10, and the insert block 32 is inserted into the first slide groove 31, and then the inner cover 20 is installed below the outer cover 10. In addition, the inner cover 20 will push the elastic push-up member 63 and abut with the elastic push-up member 63, so that the elastic push-up member 63 moves from the initial position to the avoidance position. The user can operate the handle 51 again to move, so that the transmission member 52 switches between the first position and the second position, so that the inner cover 20 rotates between the unlocked state and the locked state. During the rotation of the inner cover 20 between the unlocked state and the locked state, since the inner cover 20 is in abutment with the elastic push-up member 63, the elastic push-up member 63 can apply pressure to the inner cover 20, and can overcome the possible inclination of the inner cover 20, so as to facilitate the inner cover 20 to rotate in the horizontal direction, thereby avoiding the interference between the cover teeth and the pot teeth, so that the cover assembly can open and close the cover smoothly. Moreover, when the inner cover 20 is in the locked state, during the cooking process of the cooking utensil, since the width of the first slide groove 31 is greater than the dimension of the insert block 32 along the width direction of the first slide groove 31, as the pressure in the cooking utensil increases (i.e., upward pressure), the inner cover 20 can overcome the pressure applied to the inner cover 20 by the elastic push-up member 63 and float up steadily, and the insert block slides upward in the slide groove along the floating direction of the inner cover 20. Therefore, in the first embodiment, only the elastic ejector 63 needs to be designed to play both the limiting role and the anti-deflection role. Moreover, as the cooking utensil is pressed upward, the inner cover 20 can float up and down smoothly. One component can realize multiple functions, which not only simplifies the structure of the cover assembly, but also reduces the manufacturing cost of the cover assembly.

[0073] like Figures 1 to 10 , Fig.21 and Fig. 22As shown, the elastic push member 63 includes a push rod 631 and a third elastic member 632. A guide hole for guiding the push rod 631 is provided on the outer cover 10, and the push rod 631 includes a rod body 6311 penetrating in the guide hole and a block body 6312 connected to the rod body 6311. The inner cover 20 can abut against the rod body 6311. When the inner cover 20 is separated from the rod body 6311 and the block body 6312 is limitedly matched with the transmission member 52, the elastic push member 63 is in the initial position; when the inner cover 20 abuts against the rod body 6311 and the block body 6312 is avoided with the transmission member 52, the elastic push member 63 is in the avoidance position. The elastic push piece 63 of the above structure is adopted, and the elastic push piece 63 is inserted into the guide hole, which is convenient for installing the elastic push piece 63 and guides the movement of the elastic push piece 63 relative to the liner 14, so that the elastic push piece 63 can move smoothly and reliably between the initial position and the avoidance position.

[0074] like Figures 1 to 10 , Fig.21 and Fig. 22 As shown, the third elastic member 632 is disposed between the outer cover 10 and the elastic push member 63, and the third elastic member 632 applies an elastic force to the elastic push member 63 to keep the elastic push member 63 in the initial position. When the inner cover 20 is disassembled, the inner cover 20 is separated from the elastic push member 63, and the elastic push member 63 is acted upon by the elastic force of the third elastic member 632, so that the transmission member 52 moves from the avoidance position to the initial position and remains in the initial position, so that when the inner cover 20 is not installed, the elastic push member 63 restricts the movement of the transmission member 52, so that the handle 51 cannot be operated, and the cover assembly cannot be closed (i.e., switched from the locked state to the unlocked state), thereby avoiding the closing operation of the inner cover 20 when it is not installed.

[0075] It should be noted that the number of the elastic ejecting members 63 can be one or more.

[0076] When multiple elastic push-up members 63 are arranged at intervals around the axis of the outer cover 10, multiple elastic push-up members 63 are all in contact with the outer top wall of the inner cover 20, so that the inner cover 20 can float relative to the pot body in a direction close to or away from the outer cover 10, so that when the cover assembly is placed on the pot body and the inner cover 20 rotates relative to the outer cover 10, the elastic expansion and contraction of multiple elastic push-up members 63 can be used to overcome the possibility of the inner cover 20 tilting, thereby avoiding interference between the cover teeth and the pot teeth, so that the cover assembly can open and close smoothly. During the cooking process, as the pressure in the cooking utensil changes, the elastic expansion and contraction of multiple elastic push-up members 63 is used to make the inner cover 20 float relative to the pot body in a direction close to or away from the outer cover 10.

[0077] When an elastic ejector 63 is disposed on the outer cover and is located on a side close to the inserting block 32 , the inserting block of the inner cover can rotate along the slide groove to prevent the inner cover 20 from tilting.

[0078] When an elastic ejector 63 is set at a position away from both the insert block and the clamp block, the three components formed by the elastic ejector 63, the insert block and the clamp block (see below) keep the inner cover rotating on a plane and can also prevent the inner cover 20 from tilting.

[0079] When the inner cover 20 is circular, an elastic push piece 63 is arranged on the outer cover. In the circumferential direction of the inner cover 20, the elastic push piece 63 is spaced apart from the first slide groove 31. When the inner cover 20 rotates relative to the outer cover 10 and the plug block 32 slides in the first slide groove 31 along the rotation direction, since the elastic push piece 63 is spaced apart from the first slide groove 31, the pressure applied by the elastic push piece 63 to the inner cover 20 keeps the plug block 32 in a state of sliding in the first slide groove 31 along the rotation direction, so that the inner cover 20 can rotate smoothly.

[0080] like Figures 9 to 20 As shown, in this embodiment, a stopper 61 is provided on the inner wall of the outer cover 10, and a support surface 213 and a avoidance concave surface 214 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 23 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 23 and the pot teeth are separated (that is, the inner cover 20 is in an unlocked state), the support surface 213 and the stopper 61 are engaged. At this time, the insert block 32 is inserted into the first slide groove 31 and abuts against the lower wall surface of the first slide groove 31, so that the inner cover 20 is restricted between the stopper 61 and the lower wall surface of the first slide groove 31, thereby limiting the tilting range of the inner cover 20, and 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 under the outer cover 10, the support surface 213 cooperates with the stopper 61, and the insert block 32 is supported and guided by the first slide groove 31, and 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 to prevent tilting and shaking, and avoid the subsequent cover teeth 23 and pot teeth from being stuck together. When the cover teeth 23 and the pot teeth are buckled together (that is, the inner cover 20 is in a locked state), the avoidance concave surface 214 and the stopper 61 are avoided. In this case, when the cooking utensil is pressed upward, the pressure in the cooking utensil will push the inner cover 20 to float upward relative to the outer cover 10. The avoidance cooperation relationship between the avoidance concave surface 214 and the stopper 61 can prevent the stopper 61 from interfering with the inner cover 20, so that the inner cover 20 can float smoothly. The stopper 61 is preferably a stop rib.

[0081] like Figures 2 to 4 and Fig.10As shown, the first slide groove 31 includes an upper side wall 311 and a lower side wall 312 that are arranged opposite to each other, and the lower side wall 312 is closer to the mouth of the outer cover 10 than the upper side wall 311. The cover body assembly also includes a positioning member 62, which is arranged at the upper side wall 311. When the inner cover 20 is installed below the outer cover 10, the plug block 32 is positioned and matched with the positioning member 62, and the plug block 32 is positioned between the positioning member 62 and the lower side wall 312. In this way, the plug block 32 uses the positioning member 62 as a positioning reference, so that the inner cover 20 can swing according to this positioning reference to be installed on the outer cover 10, and the plug block 32 is prevented from sliding in the up and down directions in the first slide groove 31, which reduces the difficulty of installation, so that the inner cover 20 can be smoothly installed on the outer cover 10, thereby improving the efficiency of installation. Specifically, the positioning member 62 is arranged on the upper side wall 311. The positioning member 62 is preferably a positioning rib.

[0082] In this embodiment, the outer cover 10 includes an inner liner 14 located above the inner cover 20 and a surface cover 15 disposed above the inner liner 14, the inner liner 14 is clamped on the surface cover 15, and the first top plate 11 and the first side plate 12 are both located on the inner liner 14. The inner cover 20 includes a pot cover and an outer cover disposed above the pot cover, the outer cover is clamped on the pot cover, and the clamping block 42 and the inserting block 32 on the second top plate 21 and the second side plate 22 are both located on the outer cover. The cover teeth on the second side plate 22 are located on the pot cover. The outer cover is preferably a plastic part.

[0083] In this embodiment, in the up-down direction of the cover assembly, the lower surface of the insert block 32 protrudes downward from the lower surface of the clamp block 42. In this way, the thickness of the insert block 32 is thicker than that of the clamp block 42, and the insert block 32 can improve the structural strength of the inner cover, and it is convenient to provide a connecting structure (such as a threaded hole) on the insert block 32, so that the outer cover can be connected to the connecting structure by fasteners (such as screws) and installed together with the pot cover.

[0084] The present application also provides a cooking utensil, comprising a pot body and a cover assembly disposed on the pot body, the cover assembly being the above-mentioned cover assembly. Since the above-mentioned cover assembly can solve the problem in the related art that the pivot hole on the inner cover must be aligned with the pivot for installation, making assembly difficult, the cooking utensil comprising the cover assembly can solve the same technical problem.

[0085] In this embodiment, the pot body includes a heat-insulating cover and an inner pot arranged in the heat-insulating cover, the heat-insulating cover is provided with pot teeth, and the lower edge of the second side plate 22 is provided with cover teeth 23. In this way, the plug-in matching structure 30 and the snap-fit ​​matching structure 40 are used to match the cover teeth 23 and the pot teeth for separation or snap-fit. When the supporting member 44 is in the avoidance position, the clamping block 42 slides from the notch 43 into the second slide groove 41, and the cover teeth 23 and the pot teeth are separated. When the clamping block 42 rotates in the second slide groove 41, the cover teeth 23 and the pot teeth are snap-fitted together.

[0086] Specifically, the technical solution of this embodiment is applied, and during the process of installing the inner cover 20 below the outer cover 10, the inner cover 20 is first 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, the supporting member 44 is in the avoidance position, and 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. At this time, the support surface 213 is matched with the stopper 61, and the cover teeth 23 and the pot teeth are separated. At this time, the position of the inner cover on the outer cover 10 is as shown in FIG. Figures 13 to 16 Then, after the inner cover 20 is rotated at a preset angle H3 (preferably 30 degrees) below the outer cover 10, the cover teeth 23 and the pot teeth are buckled together, and the avoidance concave surface 214 and the stopper 61 are avoided and matched. At this time, the position of the inner cover on the outer cover 10 is as shown in FIG. Figures 17 to 20 shown.

[0087] The cooking utensil of the present embodiment is a one-piece flip-cover electric pressure cooker, the pot body also includes an outer shell arranged on the outside of the heat preservation cover, a hinge structure is arranged between the outer shell and the cover assembly, a control circuit board is arranged in the outer shell, and electrical components such as pressure control and temperature measurement are arranged in the outer cover. The one-piece setting of the one-piece flip-cover electric pressure cooker facilitates the wired connection between the electrical components in the outer cover and the control circuit board in the outer shell, thereby ensuring the reliability of the electrical connection.

[0088] Since a hinge structure is provided between the outer shell and the cover assembly, when the cover assembly is opened from the pot body, the cover assembly stands on the outer shell as a whole. At this time, the user operates the supporting member 44 to move the supporting member 44 from the supporting position to the avoiding position, so as to facilitate the inner cover to fall from the outer cover, so as to realize quick and easy removal of the inner cover from the outer cover.

[0089] Of course, in other embodiments, the cooking utensil may also be an electric rice cooker, a low-pressure rice cooker, a soymilk maker, a food processor, a cooking machine, an electric stew pot, a multi-function pot, or the like.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.
