[0033] Embodiment 1:

[0034] like Figures 1 to 4 As shown, the pot cover of the cooking utensil of this embodiment includes a surface cover 10, an inner liner 20 and a locking cover 30 arranged in sequence from top to bottom, the inner liner 20 is arranged between the surface cover 10 and the locking cover 30, the locking cover 30 is rotatably arranged on the inner liner 20, and the locking cover 30 is provided with a cover tooth. The pot cover also includes an exhaust pipe 61 and a rotating seat 50, wherein the exhaust pipe 61 is arranged at a position deviated from the rotation axis of the locking cover 30, and the exhaust pipe 61 is sealed and connected with the locking cover 30. The rotating seat 50 is rotatably arranged on the surface cover 10 and rotates synchronously with the locking cover 30, and a mounting hole 52 is arranged on the rotating seat 50, and the exhaust pipe 61 and the mounting hole 52 are sealed. A first avoidance hole 21 is arranged on the inner liner along the moving track of the exhaust pipe 61, and the exhaust pipe 61 passes through the first avoidance hole 21 and the mounting hole 52 in sequence.

[0035] By applying the technical solution of this embodiment, the exhaust pipe 61 is arranged away from the rotation axis of the lock cover 30, so that the pressure limiting valve and other structures of the cooking utensil are not restricted by the rotation axis of the lock cover 30, which is conducive to the optimization of the space arrangement on the surface cover 10, and sufficient space is reserved for structures such as the operation panel, effectively reducing the size of the pot cover. The surface cover 10, the liner 20 and the lock cover 30 are arranged in sequence from top to bottom, and the rotating seat 50 is rotatably arranged on the surface cover 10 and rotates synchronously with the lock cover 30. The exhaust pipe 61 is sealed with the lock cover 30 and the mounting hole 52 of the rotating seat 50, so that the exhaust pipe 61, the lock cover 30, and the rotating seat 50 remain relatively stationary, and can still be sealed even when the lock cover 30 rotates, so that the steam generated by the cooking utensil during cooking can be discharged through the exhaust pipe 61 without entering the cavity formed by the surface cover 10 and the liner 20. The first avoidance hole 21 provides a moving space for the exhaust pipe 61, avoiding the mutual interference between the structures during the rotation process, which affects the opening action.

[0036] like Figures 1 to 6 As shown, a pressure limiting valve 63 is provided on the exhaust pipe 61 of the present embodiment, and a pressure limiting valve cover 64 is provided on the pressure limiting valve 63. The pressure limiting valve 63 and the pressure limiting valve cover 64 rotate synchronously with the rotating seat 50. When the pressure limiting valve 63 is lifted, the gas can pass through the exhaust pipe 61 through the liner 20 and be discharged from the pot cover. When the locking cover 30 rotates, the rotating seat 50, the exhaust pipe 61, the pressure limiting valve 63, the pressure limiting valve cover 64 and other structures rotate relative to the liner 20 but keep synchronous rotation relative to the locking cover 30, so that the steam, moisture and food in the pot body will not enter the space between the surface cover 10 and the liner 20. In the above process, the first avoidance hole 21 provides a moving space for the exhaust pipe 61, avoiding mutual interference between the structures during the rotation process, which affects the opening process.

[0037] The pot cover of this embodiment also includes a lid opening handle 40, which is arranged in the rotating seat 50 and is connected to the rotating seat 50 to drive the lock cover 30 to move between the locked position and the unlocked position. The rotating seat 50 is cylindrical and has a bottom wall and a side wall. The mounting hole 52 of the rotating seat 50 is arranged on the bottom wall, and the exhaust pipe 61 and the bottom wall are sealed by a sealing ring 62. Figure 5 and Figure 6 As shown, the cylindrical rotating seat 50 always shields the lining 20 during the rotation process, keeps the pot lid closed, and prevents debris from entering the space between the lining 20 and the surface cover 10. The lid opening handle 40 is arranged along the diameter of the rotating seat 50, and the rotation axis of the lid opening handle 40 is colinear with the rotation axis of the rotating seat 50, which can provide sufficient torque when the user rotates the lid opening handle 40. The portion of the lid opening handle 40 corresponding to the pressure limiting valve 63 forms a pressure limiting valve cover 64, and the pressure limiting valve cover 64 is provided with an exhaust hole 65 at the position corresponding to the pressure limiting valve 63.

[0038] like Figure 5 and Figure 6 As shown, the locking cover 30 of this embodiment drives the buckle hook 23 to rotate through the transmission member 22. The first end of the transmission member 22 is rotatably set on the lining 20, and the second end of the transmission member 22 is provided with a guide slope that cooperates with the buckle hook 23. A long groove is provided on the transmission member 22 along the rotation direction of the locking cover 30. When the locking cover 30 rotates, the long groove is used to control the swing of the transmission member 22, and then the guide slope of the transmission member 22 cooperates with the buckle hook 23, so that the buckle hook 23 is separated from the structure on the pot body to realize opening the cover.

[0039] Embodiment 2:

[0040] The pot lid of the second embodiment provides another lid opening structure, in which the rotation axis of the lid opening handle 40 and the rotation axis of the rotating base 50 are spaced apart.

[0041] Specifically, Figures 7 to 9 As shown, the pot cover of the cooking utensil of this embodiment includes a face cover 10, an inner liner 20 and a locking cover 30 arranged in sequence from top to bottom, the inner liner 20 is arranged between the face cover 10 and the locking cover 30, and the locking cover 30 is rotatably arranged on the inner liner 20. The pot cover also includes a lid opening handle 40, a rotating seat 50 and an exhaust pipe 61. Among them, the lid opening handle 40 is rotatably arranged on the face cover 10, and the lid opening handle 40 drives the locking cover 30 to move between a locked position and an unlocked position. The rotating seat 50 is rotatably arranged on the face cover 10 and rotates synchronously with the locking cover 30. The rotating seat 50 is provided with a second avoidance hole 51, and the lid opening handle 40 is inserted in the second avoidance hole 51 to avoid interference between the lid opening handle 40 when the rotating seat 50 rotates synchronously with the locking cover 30. The exhaust pipe 61 is arranged at a position of the lock cover 30 deviating from its rotation axis. The exhaust pipe 61 passes through the rotating seat 50 and the liner 20. The liner 20 is provided with a first avoidance hole 21. The exhaust pipe 61 can move in the first avoidance hole 21. The exhaust pipe 61 and the rotating seat 50 are sealed and matched.

[0042] like Figure 7 As shown, the lining 20 of the present embodiment further includes a pivot structure 25 and a control assembly 90. The pot lid is connected to the pot body of the cooking utensil via the pivot structure 25. The control assembly 90 is disposed at the end of the lining 20. The rotating seat 50 is located between the control assembly 90 and the pivot structure 25.

[0043] Specifically, Figure 8 and Fig.12As shown, the opening handle 40 of this embodiment drives the locking cover 30 to rotate through the transmission member 22. The first end of the transmission member 22 is rotatably disposed on the lining 20. The second end of the transmission member 22 is provided with a long groove, which cooperates with the driving column of the locking cover 30 to control the rotation of the locking cover 30.

[0044] like Figures 7 to 12 As shown, the pot cover of this embodiment also includes a sealing ring 62, a pressure limiting valve and a pressure limiting valve cover 64, the sealing ring 62 is arranged on the rotating seat 50 and fixed by a pressing plate 68, the exhaust pipe 61 passes through the sealing ring 62 and the first avoidance hole 21 and is fixedly connected to the locking cover 30, the pressure limiting valve is arranged at the end of the exhaust pipe 61, the pressure limiting valve cover 64 is arranged on the surface cover 10 and is covered outside the pressure limiting valve, and the pressure limiting valve cover 64 is provided with an exhaust hole 65. When the locking cover 30 rotates, the rotating seat 50, the exhaust pipe 61, the sealing ring 62, the pressing plate 68, the pressure limiting valve and the pressure limiting valve cover rotate relative to the liner 20 but keep synchronous rotation relative to the locking cover 30, so that the steam, moisture and food in the pot body will not enter the space between the surface cover 10 and the liner 20. In the above process, the second avoidance hole 51 provides a moving space for the transmission member 22, and the first avoidance hole 21 provides a moving space for the exhaust pipe 61, so as to avoid mutual interference between the structures during the rotation process and affect the opening process.

[0045] like Figures 7 to 12 As shown, the pot cover of this embodiment further includes a rotating cover 70, which is arranged on the surface cover 10, and the rotating cover 70 is fixedly connected to the rotating seat 50. The pressure limiting valve is arranged at the end of the exhaust pipe 61 and penetrates the rotating cover 70. The rotating cover 70 is provided with a third avoidance hole 71 at a position corresponding to the second avoidance hole 51, and the cover opening handle 40 is penetrated in the third avoidance hole 71. The rotating cover 70 is conducive to keeping the outer surface of the cooking utensil flat and beautiful, and patterns can also be arranged on the rotating cover 70 to improve the aesthetics of the cooking utensil. The third avoidance hole 71 and the second avoidance hole 51 are arranged correspondingly to provide space for the cover opening handle 40 when the rotating cover 70 rotates.

[0046] In order to further keep the surface of the cooking utensil intact and beautiful, a cover 80 is arranged between the rotating cover 70 and the rotating base 50 of this embodiment. The cover 80 is provided with a mounting hole compatible with the lid opening handle 40 so that the cover 80 can be stationary relative to the surface cover 10 and can cover the second avoidance hole 51, while preventing debris from entering the pot cover through the third avoidance hole 71 and the second avoidance hole 51.

[0047] Specifically, Fig. 9As shown, the cover 10 of this embodiment includes an upper cover 11, a lower cover 12 and a receiving groove 13, the receiving groove 13 is arranged on the lower cover 12, and the control assembly 90 includes a light board 91 and a display panel 92, the light board 91 is located in the receiving groove 13, and the display panel 92 is arranged on the upper cover 11 corresponding to the light board 91. The exhaust pipe 61 deviates from the rotation axis of the lock cover 30 and is arranged toward the rear side of the pot cover, providing sufficient space for the control assembly 90 for operating the cooking utensil. The control assembly 90 is arranged on the upper cover 11 located at the top, so that the user can see the content on the display panel 92 by lowering his head slightly, thereby improving the comfort of use and user experience.

[0048] Furthermore, a swingable hook 23 is provided on the lining 20 of the present embodiment, and the hook 23 can cooperate with the pot body of the cooking utensil to prevent the pot cover from being opened relative to the pot body. To facilitate the control of the hook 23, a guide slope is further provided at the second end of the transmission member 22 of the present embodiment. When the lid opening handle 40 drives the transmission member 22 to rotate, the guide slope can pass through the hook 23 and cooperate with it to drive the hook 23 to swing, so that the hook 23 is separated from the pot body, and then the pot cover is opened.

[0049] like Figure 8 , Fig. 9 and Fig.12 As shown, the pot cover of this embodiment further includes a solenoid valve 66, a pressure-releasing swing rod 67 and a swing rod seat 69. The solenoid valve 66 is arranged on the inner liner 20, and a fourth avoidance hole 24 is arranged on the inner liner 20. The pressure-releasing swing rod 67 passes through the fourth avoidance hole 24 and is rotatably arranged on the lock cover 30 through the swing rod seat 69. The solenoid valve 66 can push the pressure-limiting valve through the pressure-releasing swing rod 67 to reduce the pressure in the pot body.

[0050] The various structures of the pot cover of the above embodiment can be connected by structures such as screw columns, and interference can be avoided by arc-shaped avoidance holes.

[0051] The present invention also provides a cooking utensil. The cooking utensil according to this embodiment (not shown in the figure) comprises a pot body and a pot cover. The pot body has a cooking cavity. The pot cover is arranged on the pot body. The pot cover is a pot cover having all or part of the above structures. The cooking utensil of this embodiment has the advantages of compact structure, small size and small space occupation.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0053] The exhaust pipe is arranged away from the rotation axis of the lock cover, so that the pressure limiting valve and other structures of the cooking utensil are not restricted by the rotation axis of the lock cover, which is conducive to the optimization of the space layout on the surface cover, and sufficient space is reserved for structures such as the operation panel, effectively reducing the size of the pot cover. The surface cover, the inner liner and the lock cover are arranged in sequence from top to bottom. The rotating seat is rotatably arranged on the surface cover and rotates synchronously with the lock cover. The exhaust pipe is sealed with the lock cover and the mounting hole of the rotating seat, so that the exhaust pipe, the lock cover and the rotating seat remain relatively still. Even when the lock cover rotates, the seal can still be maintained, so that the steam generated by the cooking utensil during cooking can be discharged through the exhaust pipe without entering the cavity formed by the surface cover and the inner liner. The first avoidance hole provides a moving space for the exhaust pipe, avoiding mutual interference between structures during the rotation process, which affects the opening action.
