[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] In some embodiments of the present utility model, such asFigure 2 An electric opening and closing pot lid includes an outer lid 1, a rotating assembly 2, and a motor 3. The motor 3 is drivingly connected to the rotating assembly 2, and the outer lid 1 is connected to the rotating assembly 2.

[0030] Specifically, the outer lid 1 is the main part of the pot lid. The design of the outer lid 1 should be able to withstand the heat and pressure during daily use. The rotating assembly 2 connects the outer lid 1 and the motor 3 and is responsible for transmitting power so that the outer lid 1 can open and close. The motor 3 provides a power source and drives the outer lid 1 to open and close through the rotating assembly 2. The outer lid 1 is connected to the rotating assembly 2 to ensure smooth rotation under the drive of the motor 3. Both the outer lid 1 and the rotating assembly 2 can be made of heat-resistant and corrosion-resistant materials such as stainless steel or special plastics. The selection of the motor 3 needs to consider its torque and power to meet the needs of opening and closing the pot lid. The position of the rotating assembly 2 needs to be determined according to the design of the outer lid 1 to ensure the accuracy and smoothness of the opening and closing actions. The user activates the motor 3 through a control component (such as a button or a touch screen). After the motor 3 starts, it drives the rotating assembly 2 to rotate, and the rotation of the rotating assembly 2 drives the outer lid 1 to open and close. Operating steps: The user presses the open lid button. After the motor 3 receives the signal, it starts and drives the rotating assembly 2, and the rotating assembly 2 drives the outer lid 1 to open. After the user finishes the operation, presses the close lid button, and the outer lid 1 slowly closes. Technical effect: The electric opening and closing pot lid of the present utility model simplifies the operation steps and improves the convenience of use. The electric mechanism reduces the direct contact between the user and the heat source and increases the safety.

[0031] Specifically, the control component can be set on the pot body or outside the pot body. When the control component is set outside the pot body, the control component is equivalent to a remote control and can remotely control the opening and closing of the outer lid 1.

[0032] In some embodiments of the present utility model, such as Figure 1 the outer lid 1 is detachably connected to the rotating assembly 2.

[0033] Specifically, the detachable connection can be in the following ways: 1. Threaded connection: A common connection method is to set threads on the rotating assembly 2, and corresponding threaded holes are provided at the corresponding positions on the outer lid 1. The user gently screws the outer lid 1 into the threads on the rotating assembly 2 to make it tightly connected to the rotating assembly 2. 2. Quick plug-and-play structure connection: Adopt a quick plug-and-play structure similar to a snap ring or a buckle, so that the user only needs to gently press or pull the outer lid 1 to fix it on or remove it from the rotating assembly 2. Technical effect: The detachable connection enables the outer lid 1 to be easily detached from the rotating assembly 2, which is convenient for cleaning, maintaining, or replacing the pot lid, thereby extending the service life of the system. The user can more thoroughly clean the connection part between the outer lid 1 and the rotating assembly 2, avoid the accumulation of food residues or dirt, and ensure food safety and hygiene. The detachable connection allows the user to replace the outer lid 1 with different styles or functions according to needs to adapt to the requirements of different dishes or usage scenarios.

[0034] The user performs corresponding connection steps according to the specific connection design. For example, for a threaded connection, the user gently screws the outer cover 1 into the thread on the rotating assembly 2 until the outer cover 1 is tightly connected to the rotating assembly 2. For a quick plug-and-play structure connection, the user can simply press or pull the outer cover 1 to fix it to or remove it from the rotating assembly 2.

[0035] In some embodiments of the present utility model, such as Figures 4 - 5 , the outer cover 1 and the rotating assembly are connected by a snap structure. The snap structure includes a snap position 242 provided on the rotating assembly and a card slot 112 recessed on the outer cover 1. The card slot 112 is cooperatively snap-connected to the snap position 242.

[0036] Specifically, the snap structure is composed of the snap position 242 on the rotating assembly 2 and the card slot 112 on the outer cover 1. The snap position 242 is a protrusion or fixed structure provided on the rotating assembly 2 and can be used to cooperate with the card slot 112 of the outer cover 1. The card slot 112 is a structure recessed on the outer cover 1 and is used to receive and snap onto the snap position 242 to achieve the connection between the outer cover 1 and the rotating assembly 2. When the outer cover 1 needs to be connected to the rotating assembly 2, the card slot 112 of the outer cover 1 is aligned with the snap position 242 on the rotating assembly 2, and then the outer cover 1 is pressed along the direction of the rotating assembly 2 to make the card slot 112 and the snap position 242 fit with each other. The shape and size of the card slot 112 are designed such that the outer cover 1 can be firmly fixed on the rotating assembly 2 to form a stable connection. The snap structure can provide a reliable connection, ensuring a stable connection between the outer cover 1 and the rotating assembly 2, making the opening and closing operations of the pot lid more stable and reliable. Through the connection of the snap structure, the disassembly and installation between the outer cover 1 and the rotating assembly 2 become more simple and fast, and the user can easily perform cleaning, maintenance or replacement of parts. The snap structure may be simpler than other connection methods, thereby reducing the manufacturing cost and improving the competitiveness of the product.

[0037] In some embodiments of the present utility model, such as Figures 2 - 3, the electric opening and closing pot lid further includes a fixed bracket 4 fixed to the pot body. The rotating assembly 2 includes a damping wheel 21, a rotating shaft 22, a transmission core bracket 23, a transmission outer shell 24, and a rotating shaft gear 25 rotatably provided on the fixed bracket 4. The rotating shaft 22 passes through the inside of the transmission core bracket 23. The damping wheel 21 is arranged inside the transmission core bracket 23 and sleeved outside the rotating shaft 22. The transmission outer shell 24 is sleeved outside the transmission core bracket 23. The end of the rotating shaft 22 protrudes outside the transmission core bracket 23, and the part of the rotating shaft 22 protruding from the transmission core bracket 23 is in transmission connection with the rotating shaft gear 25. A buckle position 242 is arranged on the outer circumference of the transmission outer shell 24. At least one installation groove is provided on the inner side wall of the transmission core bracket 23, and at least one rib cooperating with the installation groove is provided on the outer wall of the damping wheel 21. A limiting convex part is provided at the end of the damping wheel 21, and a limiting groove cooperating with the limiting convex part is provided at the end of the transmission outer shell 24. A convex platform 41 is protrudingly arranged on the top surface of the fixed bracket 4. The rotating shaft gear 25 is arranged inside the convex platform 41. One end of the rotating shaft 22 extends into the convex platform 41 to be connected with the rotating shaft gear 25. A groove 43 is recessedly arranged on the bottom surface of the fixed bracket 4, and the motor 3 is fixed in the groove 43.

[0038] Specifically, the rotating shaft 22 is clamped to the transmission core bracket 23 through a clamping pin. At least one installation groove is provided on the inner side wall of the transmission core bracket 23. At least one rib is provided on the outer circumference of the damping wheel 21. When the damping wheel 21 is inserted into the transmission core bracket 23, the rib is clamped in the installation groove. The transmission outer shell 24 is sleeved outside the transmission core bracket 23. A limiting convex part is provided at the end of the damping wheel 21, and a limiting groove is provided at the end of the transmission outer shell 24. The limiting convex part and the limiting groove are cooperatively inserted. Both ends of the rotating shaft 22 penetrate to the outside of the transmission outer shell 24. There are two convex platforms 41 on the fixed bracket 4. One rotating shaft gear 25 is arranged inside each convex platform 41. The two rotating shaft gears 25 are respectively connected to both ends of the rotating shaft 22. A driving gear and a transmission gear in transmission connection with one of the two rotating shaft gears 25 are arranged at the bottom of the fixed bracket 4. When the motor 3 is started, it drives the driving gear and the transmission gear, and the rotating shaft gear can drive the rotating shaft 22 to rotate. Under the action of the damping wheel 21, the outer cover 1 can be opened and closed smoothly.

[0039] Among them, the fixed bracket 4 is a stable support assembly fixed to the pot body, used to fix the rotating assembly 2 and the motor 3, and is made of metal or reinforced plastic. The damping wheel 21 is a part of the rotating assembly 2, used to control the opening and closing speed and buffering effect of the outer cover 1, and is made of rubber or elastic plastic, with certain elasticity and wear resistance.

[0040] The rotating shaft 22 is the main axis of the rotating assembly 2, which is used to support the damping wheel 21 and transmit the rotational force. It is made of metal and has certain rigidity and durability. The transmission core bracket 23 is the frame structure of the rotating assembly 2, which is used to fix and support the rotating shaft 22, the damping wheel 21 and the transmission outer shell 24. It is made of metal or reinforced plastic and has certain strength and stability. The transmission outer shell 24 is the outer shell structure installed outside the transmission core bracket 23, which is used to protect the rotating assembly 2 and transmit the rotational force. It is made of metal or plastic and has certain strength and durability. The rotating shaft gear 25 is a gear element fixed on the fixed bracket 4, which is used to transmit the rotational force of the motor 3 to the rotating shaft 22. It is made of metal and has certain gear design and transmission efficiency. The rotating shaft gear 25 on the fixed bracket 4 is arranged on the boss 41 of the fixed bracket 4. The transmission shaft on the transmission core bracket 23 is connected to the rotating shaft 22 through a clamping pin. The damping wheel 21 is sleeved inside the transmission core bracket 23 and outside the rotating shaft 22. The transmission outer shell 24 is sleeved outside the transmission core bracket 23. Through the structural design of the fixed bracket 4, the rotating shaft 22, the transmission core bracket 23 and the transmission outer shell 24, the stability of the entire electric opening and closing pot lid is improved. The fixed bracket 4, as the basic support component, can firmly fix the rotating assembly 2, ensuring that the entire system will not shake or loosen during operation. The design of the damping wheel 21 makes the opening and closing action smoother. The damping wheel 21 has certain elasticity and buffering performance, which can relieve the change of the movement speed of the outer lid 1 during the opening and closing process of the outer lid 1, thereby reducing the vibration and noise during the opening and closing process and improving the comfort of use. At the same time, the outer lid 1 is detachably connected to the transmission outer shell 24, which is convenient for maintenance and replacement of parts, improving the maintainability and reliability of the system. Due to the smooth and controllable opening and closing process, the risk of accidental extrusion or pinching is reduced. Through the implementation of the technical solution, the operation of the electric opening and closing pot lid becomes more convenient. The user only needs to press the switch to complete the opening and closing action without additional force and operation. At the same time, the opening and closing process is smooth and the noise is low, without causing interference, improving the comfort and convenience of use.

[0041] In some embodiments of the present invention, such as Figure 2 , two or more damping wheels 21 are provided on the rotating shaft 22, and all the damping wheels 21 are spaced apart along the axial direction of the rotating shaft 22.

[0042] Specifically, in this electric opening and closing pot lid, two or more damping wheels 21 are installed on the rotating shaft 22, and these damping wheels 21 are spaced along the axial direction of the rotating shaft 22. When the motor 3 starts, the rotating shaft 22 is driven to rotate through the transmission system, and the damping wheels 21 on the rotating shaft 22 also rotate accordingly. These damping wheels 21 interact with other components (such as the transmission housing 24, the outer lid 1, etc.) to adjust the opening and closing speed and smoothness of the outer lid 1. The spaced distribution of multiple damping wheels 21 makes the movement of the outer lid 1 more stable during the opening and closing process. Each damping wheel 21 is distributed on the rotating shaft 22, which can evenly apply damping force, effectively slowing down the change in the movement speed of the outer lid 1, thus ensuring the smoothness of the opening and closing actions. The setting of multiple damping wheels 21 shares the role of the damping force, reduces the wear degree of a single damping wheel 21, and extends the service life of the entire system. At the same time, the uniform application of the damping force also helps to reduce the risk of system failure caused by uneven wear of components, improving the stability and reliability of the system. The setting of multiple damping wheels 21 makes the damping force more uniform and more adjustable, and can better adapt to the opening and closing speed requirements of the outer lid 1 under different environments and usage conditions, improving the opening and closing efficiency. Through the distribution of multiple damping wheels 21, the noise and vibration during the opening and closing process can be effectively reduced, enhancing the comfort and quietness of use.

[0043] In some embodiments of the present utility model, such as Figure 4 , the outer lid 1 includes a lid body 12 and a fixed block 11 connected to the lid body 12. One end of the fixed block 11 protrudes outside the lid body 12, and a card slot 112 is provided at the end of the fixed block 11 away from the lid body 12.

[0044] Specifically, in this electric opening and closing pot lid, the card slot 112 on the fixed block 11 is connected to the buckle position 242 on the transmission housing 24. This connection method realizes the fixation of the outer lid 1 and the rotating component 2 by nesting the card slot 112 on the fixed block 11 and the buckle position 242 on the transmission housing 24, thus maintaining the stability and reliability of the entire system. When the motor 3 starts, the transmission housing 24, as a part of the rotating component 2, begins to rotate. Since the card slot 112 on the fixed block 11 is connected to the buckle position 242 on the transmission housing 24, the outer lid 1 also rotates accordingly, thus realizing the function of opening and closing the pot lid. Through the connection method of the card slot 112 and the buckle position 242, the firm connection between the outer lid 1 and the rotating component 2 is ensured, preventing the occurrence of detachment or loosening during the opening and closing process, and improving the stability and reliability of the system. This connection method adopts a simple structural design, is easy to operate and implement, and has high reliability, and is not easily affected by the external environment and usage conditions. The connection method of the card slot 112 and the buckle position 242 enables the connection between the outer lid 1 and the rotating component 2 to be relatively easily disassembled and maintained, facilitating daily maintenance and servicing.

[0045] In some embodiments of the present invention, Figures 5 - 6 The transmission housing 24 includes two shell parts 241 with openings at one end, the open ends of the two shell parts 241 are clamped with each other, and the ends of the two shell parts 241 facing away from the openings are provided with openings 2412, and the opposite ends of the rotating shaft 22 are respectively penetrated by the openings 2412 to extend out of the transmission housing 24, and the two sides of the fixed block 11 in the width direction are respectively provided with card grooves 112, and an avoidance groove 113 is provided between the two card grooves 112, and the avoidance grooves 113 are respectively connected with the two card grooves 112.

[0046] Specifically, the transmission housing 24 is composed of two shell parts 241 with one end open, and the open ends of the two shell parts 241 are mutually engaged to form the overall structure of the transmission housing 24. The two shell parts 241 are mutually engaged to form the overall structure of the transmission housing 24, which protects the internal transmission components. Setting the transmission housing 24 as the shell parts 241 at both ends can indeed make it convenient to sleeve the transmission housing 24 on the transmission core bracket 23. This design allows the rotating shaft 22, the damping wheel 21, the transmission core bracket 23 and the rotating shaft 22 to be fully assembled during the assembly process, and then the two shell parts 241 are respectively sleeved on the transmission core bracket 23, thereby simplifying the installation steps of the transmission housing 24 and improving the efficiency and convenience of the overall assembly. Such a design can also ensure that the connection between the transmission housing 24 and the transmission core bracket 23 is tight and stable, thereby improving the performance and reliability of the product.

[0047] Among them, an opening 2412 is set at one end of the transmission housing 24 away from the exit end, and these openings 2412 are penetrated at both ends of the rotating shaft 22, so that both ends of the rotating shaft 22 can extend out of the transmission housing 24 for easy connection or transmission with other components.

[0048] In addition, the two sides of the fixed block on the transmission housing 24 are respectively provided with card slots 112, which are used to install the fixed block. The setting of the avoidance groove 113 can ensure that during the installation process of the fixed block 11 and the transmission housing 24, the fixed block 11 is prevented from colliding with other components or structures. This can ensure the smooth assembly and avoid damage or assembly difficulties caused by structural conflicts. Through the guidance of the avoidance groove 113, the correct position of the fixed block 11 during the installation process can be ensured, thereby improving the assembly quality of the overall product. The setting of the avoidance groove 113 can also enhance the connection stability between the fixed block 11 and the transmission housing 24. Through the design of the avoidance groove 113, external vibration or impact can be absorbed to a certain extent, reducing the impact on the connection between the fixed block 11 and the transmission housing 24, and improving the stability and durability of the product.

[0049] In some embodiments of the present invention, Figure 2, a limiting portion 111 is provided on the fixing block 11, and a limiting protrusion 42 cooperating with the limiting portion 111 is provided on the fixing bracket 4.

[0050] Specifically, a limiting portion 111 is provided on the fixing block 11, and a limiting protrusion 42 cooperating with this limiting portion 111 is provided on the fixing bracket 4. When the outer cover 1 is opened to a certain extent, the limiting portion 111 abuts against the limiting protrusion 42, thereby restricting the further opening of the outer cover 1. At this time, the motor 3 still continues to operate, driving the rotating shaft 22 to continue rotating. However, since the outer cover 1 has reached the limiting position, the resistance increases, resulting in an increase in the load on the motor 3. When the load on the motor 3 exceeds a certain value, the system will trigger a protection mechanism and automatically stop the rotation of the motor 3 to prevent damage. A cooperation relationship is formed between the limiting portion 111 on the fixing block 11 and the limiting protrusion 42 on the fixing bracket 4. Through this cooperation relationship, when the outer cover 1 is opened to a certain extent, contact is formed between the limiting portion 111 and the limiting protrusion 42, thereby achieving the limiting effect and restricting the further opening of the outer cover 1. Through the cooperation of the limiting portion 111 and the limiting protrusion 42, precise control of the opening and closing range of the outer cover 1 is achieved. When the outer cover 1 is opened to the limiting position, the rotation of the motor 3 is automatically stopped, avoiding damage or safety hazards caused by the outer cover 1 exceeding the design range. When the outer cover 1 reaches the limiting position, the rotation of the motor 3 is automatically stopped, reducing unnecessary load and friction, which is beneficial to extending the service life of the motor 3 and the transmission system. By automatically stopping the rotation of the motor 3, intelligent control and protection of the system are achieved, improving the reliability and stability of the equipment. The cooperation of the limiting portion 111 and the limiting protrusion 42 makes the opening and closing operation of the outer cover 1 more convenient, without manual intervention, improving the convenience and comfort of the operation.

[0051] The outer cover 1 and the rotating assembly 2 of the present utility model are detachably connected, enabling the user to easily disassemble the outer cover for cleaning, and at the same time facilitating maintenance and replacement. The design of the detachable connection makes this electric opening and closing pot lid have a longer service life, be more durable and easy to maintain.

[0052] The above are only the principles and preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, based on the principle of the present utility model, several other variants can also be made, which should also be regarded as the protection scope of the present utility model.
