Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a lid for a pressure cooking appliance and the pressure cooking appliance itself. Background Technology

[0002] Pressure cookers are tools that increase the boiling point of water by increasing the pressure inside the pot, thereby accelerating the cooking process and making the ingredients tender and flavorful. To ensure that the internal pressure of a pressure cooker can gradually increase during cooking, the lid and pot body need to have a certain locking strength. Typically, the locking methods between the lid and pot body are either screw-on or clamp-on: the screw-on method uses the interlocking teeth of the pot body and lid to rotate and abut, ensuring a mechanically locked connection; the clamp-on method uses a clamping mechanism on the lid that abuts against the edge of the pot body when the lid is closed, creating a locking state.

[0003] In addition to the two common opening and closing methods mentioned above, there is also a pressure cooker with a pressure ring. Its lid is oval-shaped, and the opening of the pot is also oval-shaped. When the pressure cooker is closed, the lid is located inside the pot and fits against the edge of the pot at the top to complete the seal. During the cooking process, as the internal air pressure increases, the force exerted by the lid on the edge of the pot will continue to increase, and the sealing performance between the two will also be improved, ensuring the stability of the internal air pressure and avoiding air leakage.

[0004] Currently, pressure cookers with oval-shaped openings and pressure rings are not convenient enough in terms of locking and unlocking the lid during the closing process. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model discloses a lid for a pressure cooking appliance, which solves the problem of inconvenient locking and unlocking of the lid during the closing process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressure cooker lid is provided, wherein the pressure cooker has an elliptical opening and an edge surrounding the opening. The lid includes a panel and an elliptical cover body connected below the panel. A groove is formed between the panel and the cover body to fit the edge of the pot. The groove is located on the long axis side of the cover body. When the pressure cooker is closed, the cover body is contained within the pot and seals against the lower end face of the edge of the pot. The edge of the pot engages with the groove to lock the lid. The lid can be engaged or disengaged from the groove by rotation.

[0008] The pressure cooking appliance disclosed in this utility model includes a lid with a panel and a lid body, both of which are elliptical in shape. When closing the lid, first rotate the lid to adjust the relative position of the lid body and the pot opening, ensuring that the long axis of the lid body is perpendicular or nearly perpendicular to the long axis of the pot opening in the projection direction. Then, tilt the lid and insert one end of the lid body into the pot opening, allowing the entire lid body to be inserted below the pot edge. Because the locking groove is located on the side of the long axis of the lid body, the structure around the locking groove will not contact the pot edge during the insertion of the lid body into the pot, avoiding interference that could affect the user experience. After the entire lid body is inserted into the pot, return the lid to a horizontal position, then rotate the lid to gradually shorten the distance between the pot edge and the locking groove. The pot edge will gradually engage with the locking groove, completing the locking of the lid and the pot body.

[0009] Unlike existing technologies, where the lid needs to be rotated to align its long axis with the long axis of the pot opening after being inserted into the pot, the solution of this application can lock the lid after it has been inserted into the pot and the relative position of the lid and the pot has been adjusted. The lid can be locked by rotating it in the opposite direction, making it easier to operate.

[0010] Optionally, the panel includes at least two locking blocks arranged around the perimeter of the lid. When the pressure cooker is closed, the locking blocks protrude laterally from the pot opening, and the lower end of each locking block forms a locking groove with the edge of the lid. Providing at least two locking blocks allows for at least two locking grooves to be formed on the lid. The interaction of these multiple grooves with the pot edge ensures sufficient fit strength between the pot body and the lid, and good sealing performance between the lid and the pot edge. Forming locking grooves on the lid by using locking blocks reduces the manufacturing difficulty of the panel.

[0011] Optionally, the panel further includes a panel body, and an elastic element is provided between the locking block and the panel body. The elastic force of the elastic element applies pressure to the locking block in the direction of the lid. Under the action of the elastic force of the elastic element, the clamping force of the locking groove on the edge of the pot can be improved, ensuring good sealing performance between the lid and the edge of the pot. At the same time, the floating locking block allows the size of the locking groove to be adaptively adjusted according to the edge of the pot, which can reduce the precision requirements for the processing and manufacturing of components such as the locking block, the edge of the pot, and the lid.

[0012] Optionally, the vertical distance between the lower end of the locking block and the lid gradually decreases from the outside to the inside in the radial direction of the lid. This design makes it easier to align the pot edge with the slot and insert the lid, improving the locking success rate between the lid and the pot body and enhancing the user experience.

[0013] Optionally, the panel includes two locking blocks, which are distributed on both sides of the long axis of the lid and are centrally symmetrically arranged relative to the center of symmetry of the lid. The centrally symmetrical arrangement of the two locking blocks ensures that the forces acting on the two locking slots are equal. Using only two slots ensures a highly airtight circumferential seal between the lid and the pot edge when the cooking appliance is closed, improving reliability and preventing poor local sealing due to lid tilt, which could affect cooking. It also reduces the number of locking blocks on the panel, thus lowering costs. Furthermore, the centrally symmetrical arrangement enhances the aesthetics of the lid. In addition, the centrally symmetrical arrangement allows the lid to rotate, enabling the two locking slots to simultaneously move closer to or further away from the pot edge.

[0014] Optionally, the panel includes two sets of locking blocks, with at least one locking block in each set. The two sets of locking blocks are located on both sides of the long axis of the lid and on and / or on both sides of the short axis of the lid. Designing multiple locking blocks allows multiple slots to be formed on the lid, simultaneously distributing the force and ensuring a highly airtight circumferential seal between the lid and the pot edge when the cooking appliance is closed. This prevents poor local sealing due to lid tilting, which could affect cooking. The positioning of the two sets of locking blocks ensures that when the lid rotates, multiple slots simultaneously move closer to or further away from the pot edge.

[0015] Optionally, the panel includes a panel body and a locking block that protrudes laterally from the pot opening when the pressure cooker is in the closed state. A locking groove is formed between the lower end of the locking block and the edge of the lid. The panel body protrudes laterally from both sides of the lid in the radial direction to form a stop portion. The stop portion is located above the locking block and protrudes laterally from it. The stop portion is stopped by the pot edge when the pot edge retracts from the locking groove, preventing the lid from tilting and falling into the pot. The stop portion can abut against the pot edge when the lid is unlocked and the lid is not lifted by external force, allowing the pot edge to support the lid and prevent it from falling into the pot, thus preventing food and the lid from getting dirty. The horizontally protruding stop, extending beyond the locking block, remains above the pot's edge even after the lid and pot body are unlocked. This ensures the pot's edge can contact the stop and support the lid. Furthermore, the stop, being higher than the locking block, maintains a significant vertical distance from the pot's edge, preventing it from interfering with the lid's insertion into the pot during closing. In addition, the stop also conceals the locking block, optimizing the lid's appearance.

[0016] Optionally, the lid also includes a sealing ring fitted around the periphery of the lid body. The edge of the lid body extends towards the panel to form a flange that radially stops the sealing ring. When the pressure cooker is closed, the sealing ring is pressed between the lid body and the edge of the pot to provide a circumferential seal. The sealing ring provides a circumferential seal between the pot edge and the lid body, preventing air leakage during cooking. The flange formed on the lid body positions the sealing ring, preventing it from moving radially and detaching from the lid body under pressure from the lid body and the pot edge. In addition, the flange's stopping effect reduces the radial deformation of the sealing ring, preventing excessive deformation and breakage.

[0017] This utility model also discloses a pressure cooking appliance, including a pot body and a lid that fits onto the pot body. The upper edge of the pot body extends inward to form a rim, which forms an elliptical opening. The lid is the lid of the aforementioned pressure cooking appliance. Using this lid makes opening and closing the pressure cooking appliance more convenient, improving the user experience.

[0018] Optionally, a positioning element is provided on the edge of the pot. This positioning element stops the pot lid during the rotational locking process between the lid and the pot body, keeping the pressure cooking appliance in a closed state. The lid and pot body lock together by rotating the pot edge into a slot. However, the engagement between the pot edge and the slot is not instantaneous but a continuous process. The deeper the pot edge engages in the slot, the stronger the lock. By setting the positioning element to stop the lid after it has rotated a certain angle, the user is reminded that the engagement between the pot edge and the slot is at its optimal state, thus improving the user experience.

[0019] Optionally, a portion of the panel protrudes laterally from the pot rim, and the positioning member protrudes from the upper surface of the pot edge. During the rotational locking process of the pot lid and pot body, the positioning member abuts against the panel to stop the pot lid from rotating. During this process, the portion of the panel protruding from the pot rim will continuously approach the positioning member. When this portion abuts against the positioning member, the obstructed pot lid stops rotating. This eliminates the need for an additional structure on the pot lid to cooperate with the positioning member, resulting in a simple structure and eliminating the need for a corresponding unlocking mechanism.

[0020] These features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. The preferred embodiments or means of this utility model will be shown in detail in conjunction with the accompanying drawings, but are not intended to limit the technical solutions of this utility model.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0037] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0038] Reference Figures 1 to 9 This utility model discloses a lid for a pressure cooking appliance. The pressure cooking appliance includes a pot body 100, with a cooking cavity 110 formed inside the pot body 100 for cooking food. The upper end of the pot body 100 is open and its upper edge extends inward to form a pot edge 120, which forms an elliptical pot opening 130. The lid 200 includes a panel 300 and a cover body 400 connected below the panel 300. The cover body 400 is elliptical, and the length of the major axis of the cover body 400 is greater than the length of the major axis of the pot opening 130, and the length of the minor axis is greater than the length of the minor axis of the pot opening 130. When the pressure cooker is in the closed position (the pot body 100 and the pot lid 200 are closed and locked), the lid 400 is accommodated in the cooking chamber 110, and the edge of the lid 400 is sealed to the lower end of the pot edge 120. A sealing ring 410 is provided between the two to provide a circumferential seal. As cooking proceeds, the air pressure in the cooking chamber 110 gradually increases. Under the action of air pressure, the pot lid 200 tends to move outward from the cooking chamber 110, which gradually increases the pressure between the lid 400 and the pot edge 120. Under the action of the gradually increasing pressure, the sealing ring 410 can provide a stronger circumferential seal to further increase the air pressure in the cooking chamber 110.

[0039] like Figure 3 As shown, Figure 3 The dotted line L1 points to the major axis of the pot opening, and the dotted line L2 points to the minor axis of the pot opening.

[0040] like Figure 4 As shown, Figure 4 The dotted line L3 points to the major axis of the cover, and the dotted line L4 points to the minor axis of the cover.

[0041] The lid also includes a locking structure, which locks the pot body 100 and lid 200 together after they are closed, and keeps the cooking cavity 110 sealed after locking. In the prior art, handles are typically provided on the lid and pot body, and locking the handles locks the pot body and lid. In this application, the locking structure is provided on the lid 200, and is a groove 210 formed between the panel 300 and the lid 400 that fits the edge 120 of the pot (e.g., a slot 210). Figure 8 As shown, Figure 8The area enclosed by the rectangular frame is the slot 210. The slot 210 is located on the long axis side of the lid 400. When the pressure cooker is in the closed state, the pot edge 120 is inserted into the slot 210 to lock the pot body 100 and the lid 200. By rotating the lid 200 relative to the pot body 100, the pot edge 120 can be inserted into or removed from the slot 210, thereby locking and unlocking the pot body 100 and the lid 200.

[0042] Specifically, when closing the lid, first rotate the lid 200 to adjust the relative position of the lid body 400 and the pot opening 130, so that the long axis of the lid body 400 and the long axis of the pot opening 130 are perpendicular or nearly perpendicular in the projection direction. Then, tilt the lid 200 and insert one end of the lid body 400 into the pot opening 130, so that the entire lid body 400 enters the cooking cavity 110. Since the slot 210 is located on the side of the long axis of the lid body 400, the structure around the slot 210 will not come into contact with the pot edge 120 during the process of the lid body 400 entering the cooking cavity 110 (e.g., ...). Figure 9 As shown, after the lid is inserted into the pot body, there is still a lateral gap between the pot edge and the slot, to avoid interference during the insertion of the lid 400 into the cooking cavity 110 and affecting the user experience. After the entire lid 400 is inserted into the cooking cavity 110, the lid 200 is returned to a horizontal position, and then the lid 200 is rotated to gradually shorten the gap between the pot edge 120 and the slot 210. The pot edge 120 will gradually lock into the slot 210, completing the locking of the lid 200 and the pot body 100. Unlike the prior art, in the prior art, after the lid is inserted into the pot body, it is necessary to first rotate the lid to make the long axis of the lid coincide with the long axis of the pot opening before the locking step is performed. The solution of this application can complete the locking during the adjustment of the relative position of the lid 200 and the pot body 100 after the lid 400 is inserted into the pot body 100. Rotating the lid 200 in the opposite direction can release the lock between it and the pot body 100, making it easier to operate.

[0043] The panel 300 includes a panel body 310 and a locking block 320 disposed on the panel body 310. The locking block 320 is disposed on the periphery of the lid 400 and forms a locking groove 210 between the lid 400 and the edge of the lid 400. When the pressure cooking appliance is in the closed state, the locking block 320 protrudes laterally from the pot opening 130, thus forming a locking groove 210 that allows the pot edge 120 to engage. There are at least two locking blocks 320, so that the lid 200 has at least two locking grooves 210. Through the cooperation of multiple locking grooves 210 with the pot edge 120, sufficient fit strength between the pot body 100 and the lid 200 can be ensured, and good sealing performance can be achieved between the lid 400 and the pot edge 120. By setting the locking blocks 320 to form the locking groove 210 on the lid 200, the manufacturing difficulty of the panel 300 can be reduced.

[0044] Of course, it is also conceivable that the structure of the panel body can be designed to directly form a slot between the panel body and the cover.

[0045] Reference Figures 5 to 7 Based on the above embodiments, in one embodiment, an elastic element 220 is provided between the locking block 320 and the panel body 310, allowing the locking block 320 to float. The elastic force of the elastic element 220 can apply pressure to the locking block 320 in the direction of the cover 400, which can improve the clamping force of the slot 210 on the pot edge 120 and ensure good sealing performance between the cover 400 and the pot edge 120. At the same time, the floating locking block 320 allows the size of the slot 210 to be adaptively adjusted according to the pot edge 120, which can reduce the precision requirements for the processing and manufacturing of components such as the locking block 320, the pot edge 120, and the cover 400.

[0046] The elastic element 220 can remain in a compressed state, and its elastic force always acts on the locking block 320. When the pot edge 120 is not locked into the slot 210, the locking block 320 can abut against the lid 400. As the pot edge 120 is locked in, the locking block 320 will be gradually pushed away from the lid 400.

[0047] The elastic element 220 is preferably a spring. Other elastic materials, such as sheet metal, silicone pads, etc., can also be used.

[0048] Of course, it is conceivable that when the pot edge 120 is not engaged in the slot 210, the locking block 320 can maintain a distance from the lid 400, and the distance is less than the thickness of the pot edge 120. When the pot edge 120 is engaged in the slot 210, the elastic element 220 is compressed and deformed, applying an elastic force to the locking block 320. Alternatively, the distance between the slots 210 can be maintained by providing a limiting structure for the locking block 320 on the lid 200, so that the pot edge 120 can be engaged in the slot 210.

[0049] To improve the user experience, refer to Figures 5 to 7 Based on the above embodiments, in one embodiment, the vertical distance between the lower end of the locking block 320 and the lid 400 gradually decreases from the outside to the inside in the radial direction of the lid 400. This design allows the locking groove 210 to have an inlet 211 on the side facing the pot edge 120, with a size (thickness) exceeding that of the pot edge 120. The pot edge 120 can easily align with and be inserted into the locking groove 210. Even if the height of the lid 200 is too low, as long as the pot edge 120 can enter the inlet 211 of the locking groove 210, the height of the lid 200 will adjust accordingly as the pot edge 120 is inserted into the locking groove 210, thus improving the locking efficiency between the lid 200 and the pot body 100 and enhancing the user experience.

[0050] The lower end of the slot 210 can be configured as a sloping or curved structure to form the aforementioned inlet 211.

[0051] Unlike the above embodiments, in another embodiment, the locking block is fixedly installed on the panel body. The vertical distance between the lower end of the locking block and the cover gradually decreases from the outside to the inside in the radial direction of the cover. As the pot edge is inserted into the locking groove, the size of the locking groove (in the thickness direction of the pot edge) gradually decreases as the insertion depth increases, so that the force between the pot edge and the locking block and the cover becomes greater and greater, thereby achieving the locking of the pot lid and the pot body.

[0052] The lower end of the card slot can be designed as a beveled or curved surface to form a card slot with gradually decreasing size.

[0053] Reference Figure 4 and Figure 5 Based on the above embodiments, in one embodiment, preferably, the number of card blocks 320 on the panel 300 is two, and the two card blocks 320 are arranged in a centrally symmetrical manner with respect to the center of symmetry of the cover 400.

[0054] The cover 400 is elliptical in shape, and the ellipse has several geometric quantities: major axis, minor axis, foci, etc. The center of symmetry of the cover 400 is the midpoint between the two foci of the ellipse. Figure 4 In the diagram, the intersection of L3 and L4 is the center of symmetry of the lid. The two symmetrically positioned locking blocks 320 ensure that the forces acting on the two locking slots 210 are equal. Using only two locking slots 210 ensures a highly airtight circumferential seal between the lid 200 and the pot edge 120 when the cooking appliance is closed, improving reliability and preventing poor local sealing due to lid tilt, which could affect cooking. It also reduces the number of locking blocks 320 on the panel 300, thus lowering costs. Furthermore, the symmetrical design enhances the aesthetics of the lid 200.

[0055] In addition, the centrally symmetrical arrangement ensures that the rotation of the lid 200 allows the two slots 210 to simultaneously move closer to or further away from the edge of the pot 120.

[0056] Preferably, the two locking blocks 320 are disposed on the short axis of the lid 400. During the process of the lid 400 being inserted into the cooking cavity 110, the furthest horizontal distance between the lid 400 and the edge of the pot 120 is the distance between the short axis end of the lid 400 and the long axis end of the pot opening 130. The locking blocks 320 are disposed on the short axis of the lid 400 to ensure that there is sufficient distance between the locking blocks 320 and the edge of the pot 120 during the process of the lid 400 being inserted into the cooking cavity 110, so as to prevent interference.

[0057] In addition, the two locking blocks 320 can also be respectively set on both sides of the short axis of the cover 400.

[0058] Reference Figure 8 Unlike the above embodiments, in another embodiment, the panel 300 has at least three locking blocks 320, which are divided into two groups. One group of locking blocks 320 is located on one side of the long axis of the cover 400, and the other group of locking blocks 320 is located on the other side of the long axis of the cover 400. The same group of locking blocks 320 is located on the same side of the short axis of the cover 400, and the two groups of locking blocks 320 are located on opposite sides of the short axis.

[0059] Of course, it is conceivable that the 320 card block could also be set on the short axis.

[0060] like Figure 8 As shown, Figure 8 C1, C2, C3, C4, C5, and C6 refer to the optional placement positions of the card blocks. C1 to C3 represent one set of optional placement positions, while C4 to C6 represent another set. It should be understood that the optional positions C2, C3, C4, and C5 are not fixed as shown in the diagram; other surrounding positions can also be selected, and the number of these positions is not fixed. Figure 8 This is for illustrative purposes only.

[0061] The design of multiple locking blocks 320 enables the formation of multiple locking grooves 210 on the lid 200 to simultaneously distribute the force, ensuring a highly airtight circumferential seal between the lid 200 and the edge of the pot 120 when the cooking utensil is closed, thus preventing the lid 200 from tilting and causing poor local sealing, which would affect cooking.

[0062] The positioning of the two sets of locking blocks 320 ensures that the rotation of the pot lid 200 allows multiple locking slots 210 to simultaneously move closer to or further away from the pot edge 120.

[0063] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5Based on the above embodiments, in one embodiment, the panel body 310 protrudes in the short axis direction of the cover 400 to form a stop portion 330. The stop portion 330 is located above the locking block 320 and protrudes laterally from the locking block 320. When the pot edge 120 is disengaged from the locking groove 210, the stop portion 330 is stopped by the pot edge 120 to prevent the pot lid 200 from tilting and falling into the pot body 100. The stop portion 330 can abut against the pot edge 120 when the pot lid 200 is unlocked from the pot body 100 and the pot lid 200 is not lifted by external force, so that the pot edge 120 can support the pot lid 200 and prevent the pot lid 200 from falling into the pot body 100, thus preventing food and the pot lid 200 from being soiled. The stop portion 330, which protrudes laterally from the locking block 320, can still protrude from the edge of the pot 120 after the lid 200 and the pot body 100 are unlocked, ensuring that the edge of the pot 120 can contact the stop portion 330 and support the lid 200. At the same time, there is a large vertical distance between the stop portion 330, which is higher than the locking block 320, and the edge of the pot 120. During the process of closing the lid, the stop portion 330 will not contact the edge of the pot 120 and cause interference when the lid 400 is inserted into the pot body 100.

[0064] The stop part 330 can also be used as a handle, making it easy for the user to apply force to rotate the pot lid 200.

[0065] In addition, the stop part 330 can also cover the card block 320, optimizing the appearance of the pot lid 200.

[0066] The elastic element 220 is disposed between the stop part 330 and the locking block 320.

[0067] Reference Figure 5 and Figure 7 Based on the above embodiments, in one embodiment, the edge of the cover 400 extends towards the panel 300 to form a flange 420 for radially stopping the sealing ring 410. The flange 420 can position the sealing ring 410, preventing it from moving radially and detaching from the cover 400 under the pressure of the cover 400 and the pot edge 120. In addition, the stopping effect of the flange 420 can also reduce the radial deformation of the sealing ring 410, preventing the sealing ring 410 from breaking due to excessive deformation.

[0068] Reference Figure 5 Based on the above embodiments, in one embodiment, the panel 300 is further provided with a plurality of valve chambers 340, and the cover 400 is provided with through holes 430 corresponding to the valve chambers 340 and communicating with the valve chambers 340. The valve chambers 340 can be used to assemble conventional valves of pressure cooking appliances such as pressure relief valves and safety valves.

[0069] Reference Figure 5Based on the above embodiments, in one embodiment, a handle 350 is also provided protruding from the upper part of the panel 300. The handle 350 is used to lift the pot lid 200. The handle can also be made into a longer handle, which makes it easier for the user to grip and apply force to rotate the pot lid.

[0070] Reference Figures 1 to 3 , Figure 6 This utility model embodiment also discloses a pressure cooking appliance, which includes a pot body 100 and a lid 200 that fits onto the pot body. The pot body 100 has a cooking cavity 110 for cooking food. The upper end of the pot body 100 is open, and its upper edge extends inward to form a pot rim 120, which forms an elliptical pot opening 130. The lid 200 is the same as the lid disclosed in the aforementioned embodiment. By adopting the lid 200 disclosed in the above embodiment, the pressure cooking appliance makes closing and opening the lid more convenient, improving the user experience.

[0071] Reference Figure 1 Based on the above embodiments, in one embodiment, a positioning element 140 is provided on the edge of the pot 120. The positioning element 140 stops the lid 200 during the rotation and locking process between the lid 200 and the pot body 100, keeping the pressure cooking appliance in a closed state. The lid 200 and the pot body 100 are locked by rotating the edge of the pot 120 into the slot 210. However, the engagement between the edge of the pot 120 and the slot 210 is not a direct process, but a continuous process. The deeper the edge of the pot 120 is engaged in the slot 210, the stronger the lock. By setting the positioning element 140 to stop the lid 200 after it has rotated a certain angle, the user is reminded that the engagement between the edge of the pot 120 and the slot 210 is at its most perfect state, which improves the user experience. Moreover, the structure is simple and does not require a corresponding unlocking structure.

[0072] Preferably, the positioning element 140 protrudes from the upper surface of the pot edge 120 and can be a protruding structure such as a boss or a protruding column. The positioning element 140 stops the pot lid 200 from rotating by abutting against the pot lid 200.

[0073] It is conceivable that other means could be used to stop the rotation of the lid 200, such as a magnetic component, to provide feedback to the user and remind them; alternatively, markings could be set on the lid 200 and the edge of the pot 120 to remind the user.

[0074] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
