[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this invention or the accompanying drawings are used to distinguish different objects rather than to describe a specific order. The cold water mentioned in the specification and claims of this invention includes water at room temperature.

[0035] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Reference Figures 1 to 5 The first embodiment of the present application proposes a cooking device that can automatically open the lid for cooking, which includes a pot shell 10, a lid shell 20 hingedly connected to the pot shell 10, a pot body 30 detachably embedded in the pot shell 10, an electric opening portion 40, a support base 50, a rotating fixing portion 60, a buckling component 70 and a hooking component 80.

[0038] The electric opening portion 40 and the support base 50 are both fixed in the pot shell 10, the rotating fixing portion 60 is rotatably fixed on the support base 50, and the two ends of the fastening component 70 are respectively connected to the rotating fixing portion 60 and the hooking component 80.

[0039] The hooking member 80 is engaged with the buckling member 21 in the cover housing 20 .

[0040] The unlocking end 45 of the electric unlocking portion 40 is connected to the middle portion of the fastening component 70 .

[0041] When the temperature inside the pot body 30 reaches a preset temperature, the electric unlocking unit 40 drives the fastening component 70 to rotate away from the fastening member 21 with the rotating fixing portion 60 as the rotation point, so that the hooking component 80 is unlocked and away from the fastening member 21 .

[0042] Specifically, the pot shell 10 serves as the main body of the cooking device, which is used to accommodate the pot body 30 and other components. The lid shell 20 is hingedly connected to the pot shell 10 to form a closed space for cooking. When the cooking temperature in the pot body 30 reaches the preset cooking temperature for opening the lid, the electric opening part 40 triggers the automatic lid opening operation. Then, through the interaction with the fastening part 70, the fastening part 70 rotates downward with the rotating fixing part 60 as the fixed point (if the matching point of the electric opening part 40 and the fastening part 70 is on the side of the fastening assembly facing away from the pot body 30, then the fastening part 70 moves toward the pot body 30 at this time), so that the fastening part 70 gradually moves away from the fastening part 21. At the same time, driven by the fastening part 70, the hooking part 80 also rotates away from the fastening part 21 with the rotating fixing part 60 as the fixed point, thereby automatically completing the lid opening operation of the pot shell 10 and the lid shell 20.

[0043] The support base 50 provides a stable support point for the rotating fixing portion 60 , ensuring that the rotating fixing portion 60 can rotate smoothly, so that the opening and closing process of the cover shell 20 becomes smooth and reliable.

[0044] To sum up, the cooking device that can automatically open the lid and cook realizes the automatic opening of the lid and cooking function, thereby avoiding the problem of reducing the heating power to ensure that the objects in the pot body 30 do not overflow. It not only improves the user's cooking convenience, safety and experience, but also improves cooking efficiency and quality through automatic control.

[0045] In some embodiments, the electric buckle opening portion 40 and the support seat 50 are both fixed in the cover shell 20 , and the buckle member 21 is provided in the pot shell 10 .

[0046] Specifically, the cover shell 20 and the pot shell 10 are both double-layer shell structures, and the electric buckle part 40, the support seat 50 and the buckling component 70 are all located between the two layers of the pot shell 10; a third clearance hole 22 is provided at the position where the cover shell 20 and the pot shell 10 are buckled together, and the buckle part 21 extends to the hole wall of the third clearance hole 22.

[0047] refer to Figures 2 to 5 The electric opening part 40 includes a driving support 41, a driving member 42, a push rod 43 and a return spring 44. The driving support 41 is fixed in the pot shell 10, and the driving member 42 is fixed on the driving support 41. One end of the push rod 43 is driven and connected to the driving member 42 and connected to one end of the return spring 44. The other end of the push rod 43 is the opening end 45, and the other end of the return spring 44 is fixed to the driving support 41.

[0048] In this embodiment, the drive support 41 serves as a fixed base for the entire electric opening portion 40, allowing the electric opening portion 40 to be securely mounted within the pot housing 10. The drive member 42 is the core power source for the electric opening portion 40 and is typically driven by a motor, electromagnet, or other electric device. Upon receiving a signal from the temperature sensor 100, it generates a corresponding power output to drive the push rod 43 to move. The push rod 43 acts directly on the first opening bevel 71 of the fastening component 70 to achieve the opening operation between the pot housing 10 and the lid housing 20. The return spring 44 is used to provide a reverse return force to the push rod 43 after the drive member 42 stops working, allowing it to automatically return to its initial position.

[0049] Specifically, the driving component 42 is a solenoid valve.

[0050] refer to Figures 4 and 5 A first opening slope 71 is provided at the middle of the fastening component 70 , and a second opening slope 451 is provided at the opening end 45 . The second opening slope 451 is parallel to and abuts against the first opening slope 71 .

[0051] When the temperature inside the pot body 30 reaches the preset temperature, the second opening slope 451 moves from the bottom of the slope of the first opening slope 71 to the top of the slope of the first opening slope 71, so that the fastening component 70 rotates away from the fastening part 21 with the rotating fixing part 60 as the rotation point, so that the hooking component 80 is unlocked and away from the fastening part 21.

[0052] In this embodiment, the second opening bevel 451 is parallel to the first opening bevel 71, ensuring that the two can form a stable sliding fit when in contact, and helps to reduce friction between the contact surfaces, because when the bevels come into contact, a force component is generated along the direction of the bevel, which facilitates sliding rather than direct confrontation. In addition, the design of the second opening bevel 451 can also disperse contact pressure and reduce local wear. Because the second opening bevel 451 is parallel to the first opening bevel 71, they can maintain a stable relative position when in contact and are less likely to shift or misalign. This helps to ensure the accuracy and consistency of the opening action.

[0053] The stability, reliability and durability of the buckle opening action are thereby improved. By designing the two inclined planes to be parallel, a stable sliding fit between the push rod 43 and the buckle engaging member 70 is achieved.

[0054] refer to Figure 3 The cooking device with automatic lid opening and cooking further includes a first elastic member 90 , the two ends of which are respectively fixed to the pot shell 10 and the side of the fastening member 70 facing away from the fastening member 21 .

[0055] In this embodiment, when the fastening component 70 is subjected to an external force (such as the action of the electric buckle release unit 40 or the manual push member 110) and moves away from the fastening member 21, the hook member 80 is located at the end of the fastening component 70 away from the rotational fixing portion 60. Therefore, the hook member 80 is also moved away from the fastening member 21. In other words, when the hook member 80 rotates away from the fastening member 21, the first elastic member 90 is stretched or compressed, storing elastic potential energy. Once the external force disappears, the first elastic member 90 releases the stored energy, pushing the fastening component 70 and the hook member 80 back to their original position.

[0056] refer to Figure 2 The cooking device that can automatically open the lid and cook also includes a temperature sensor 100, which is fixed in the lid shell 20 and communicatively connected to the electric opening buckle part 40. Its temperature measuring end passes through the inner wall of the lid shell 20 and extends into the pot body 30, and is used to detect the temperature inside the pot body 30.

[0057] In this embodiment, the temperature sensor 100 is used to detect the cooking temperature of the object in the pot body 30. When the object in the pot body 30 is at a boiling temperature, it is the preset temperature for opening the lid and cooking (that is, the preset temperature); when the temperature detected by the temperature sensor 100 reaches the preset temperature, the temperature sensor 100 will send a signal to the electric opening part 40 to trigger the automatic lid opening operation.

[0058] refer to Figures 2 to 5 The cooking device capable of automatically opening the lid for cooking further includes a hand-pressing member 110 , the two ends of which are respectively fixed to the fastening member 70 and the rotating fixing portion 60 .

[0059] When automatic lid opening and cooking is required, the hand button 110 is pressed to rotate the hooking member 80 away from the buckling member 21 with the rotation fixing portion 60 as the rotation point.

[0060] In this embodiment, a manual lid opening operation is added as a backup or supplement to the electric buckle opening portion 40, ensuring that the user can still open the lid shell 20 when the cooking device is not powered on or the electric buckle opening portion 40 fails.

[0061] refer to Figure 3 The cooking device with automatic lid opening and cooking further includes a second elastic member 120 , the two ends of which are respectively fixed to the pot shell 10 and the hand-pressing member 110 .

[0062] In this embodiment, pressing the push button 110 compresses both the first elastic member 90 and the second elastic member 120, causing the hook member 80 to pivot away from the fastening member 21 about the rotational fixing portion 60. Once the user releases the push button 110, the first elastic member 90 and the second elastic member 120 release their stored energy, pushing the push button 110, the fastening member 70, and the hook member 80 back into position. This helps ensure that the fastening member 70 quickly and reliably returns to its original position after manual lid opening.

[0063] refer to Figure 3 The outer wall of the pot shell 10 adjacent to the hand-pressing member 110 is provided with a first clearance hole 11. The first clearance hole 11 is used to make way for the hand-pressing member 110 to ensure the normal use of the hand-pressing member 110.

[0064] refer to Figures 1 to 3 One end of the cover shell 20 is hinged to the first side of the top of the pot shell 10, and the other end of the cover shell 20 is fastened to the second side of the top of the pot shell 10 through the hook component 80 and the buckle 21.

[0065] A second clearance hole 12 is provided on the first side of the top of the pot shell 10, and the hooking member 80 passes through the second clearance hole 12. A third clearance hole 22 is provided at a point where the cover shell 20 and the hooking member 80 are buckled and connected.

[0066] The buckle member 21 extends to a first side wall of the third paving hole 22 . The first side wall of the third paving hole 22 and the electric buckle opening portion 40 are both located on the same side of the buckling component 70 .

[0067] When the hooking member 80 and the buckling member 21 are buckled with each other, the hooking member 80 passes through the third clearance hole 22 .

[0068] In this embodiment, when the cooking device needs to be closed, the user can rotate the cover shell 20 to the closed position (i.e., the hooking component 80 is aligned with the second clearance hole 12 and the third clearance hole 22), and then the user can continue to press down the cover shell 20 (or press the hand button 110) to make the hooking component 80 pass through the second clearance hole 12 and enter the third clearance hole 22, and then the hooking component 80 and the buckle 21 at the third clearance hole 22 are buckled with each other.

[0069] Specifically, one end of the cover shell 20 is hinged to one end of the pot shell 10 through a hinge spring 130 .

[0070] refer to Figures 2 to 5 The hooking component 80 includes a connecting end 81 and a buckling end 82. One end of the connecting end 81 extends on the buckling component 70, and the other end is integrally formed and intersects with the buckling end 82. The buckling end 82 is buckled with the buckle 21.

[0071] In this embodiment, the connecting end 81 and the buckling end 82 are connected in a hook shape.

[0072] Specifically, a guide slope 140 is provided on the top surface of the locking end 82, away from the connecting end 81. The bottom of the guide slope 140 is located near the locking member 21. To close the cooking device, the lid housing 20 can be directly pressed downward, causing the locking member 21 to move from the top of the guide slope 140 to the bottom of the guide slope 140, ultimately locking the locking member 80 with the locking member 21. This facilitates the closing operation of the lid housing 20 and the pot housing 10.

[0073] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms.
