Description

Technical Field

[0001] This invention relates to the field of cooking appliance technology, and more particularly to a pressure cooker lid assembly. Background Technology

[0002] The main function of the pressure cooker's steel lid is to fasten together with the insulation cover, forming a sealed space with the inner pot, the inner pot sealing ring, and the steel lid. When the pressure cooker is working, pressure is generated inside the pot, and the temperature inside the pot exceeds 100°C, achieving rapid cooking of food. This advantage of the pressure cooker is especially evident when used at high altitudes.

[0003] Existing pressure cookers generally have a lid assembly that is separate from the pot body, so there is no problem with cleaning. The screw-fixed structure is simple, and the plastic parts are not easy to detach after being heated, resulting in high reliability.

[0004] Some steel lid components are integrated with the pot body (the lid can be lifted up after the pot lid component is rotated). This design generally makes it impossible to remove the steel lid component, which makes cleaning difficult (it can only be wiped with a wet towel).

[0005] The existing integrated pressure cooker technology has been widely reported to have a problem where the steel lid cannot be removed for cleaning, and it cannot be rinsed with water, making it difficult to clean the steel lid thoroughly. To solve this problem, new products are now generally designed with a detachable structure.

[0006] Currently, there are two main types of detachable steel lid structures: 1) The steel lid and rotating parts are fixed together using nuts and bolts. This structure has several drawbacks: 1) The lid needs to have holes, and if the seal is not good, it is easy to leak air; 2) The nuts and bolts must meet food-grade standards and cannot rust, which is costly. Summary of the Invention

[0007] The purpose of this invention is to provide a pressure cooker lid assembly, which, through a steel lid and steel lid fittings, allows the assembly and disassembly of the lid assembly to be completed simultaneously with the assembly or disassembly of the handle and the lid, thus facilitating the cleaning of the lid assembly.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0009] A pressure cooker lid assembly includes a steel lid, wherein the steel lid is partially recessed to form a mounting base; The mounting base is equipped with a handle, and a steel cover assembly is provided near the steel cover side of the handle. In the steel cover assembly or the mounting base, one forms an assembly part, and the other forms an assembly locking groove. The assembly part and the assembly locking groove are assembled or disassembled within a set range in the mounting base by applying external force, touching a button, or rotating, so as to realize the installation and disassembly of the steel cover.

[0010] Preferably, a stepped gap is formed between the mounting base and the handle.

[0011] Preferably, the assembly part with a force-bearing surface is formed by a partial protrusion inside the assembly base, and the assembly part is recessed inward in the circumferential direction to form a snap-fit ​​groove. The assembly locking groove that cooperates with it is formed on the handle by a slider assembly.

[0012] Preferably, a first guide surface and a second guide surface are formed on the assembly part, and the first guide surface and the second guide surface form the assembly guide trajectory and disassembly guide trajectory of the slider assembly.

[0013] Preferably, it further includes guide rail assemblies mounted facing each other, the slider assembly moves within a set range of the guide rail assembly, and the projection surface formed by the mounting base covers the projection surface formed by the guide rail assembly.

[0014] Preferably, the assembly part is a button that slides along the assembly base within the assembly base, the side of the button extends to form a locking part, the handle is provided with a sliding groove and a latch that moves along the sliding groove, and the latch matches the locking part.

[0015] Preferably, the surface of the steel cover protrudes to form a slide rail surface facing the slide groove, and the projection surface of the button covers the slide rail surface.

[0016] Preferably, the slide groove is perpendicular to the slide rail surface, a positioning element is provided on the slide groove, the latch is partially hollowed out to form a sliding cavity, and the positioning element is located inside the sliding cavity.

[0017] Preferably, the assembly part is a fastener provided on the handle, the assembly base has a receiving cavity and an assembly slot on the receiving cavity, the fastener rotates along the receiving cavity, so that the fastener is misaligned or aligned with the assembly slot, so as to achieve locking or unlocking.

[0018] Preferably, along the outer periphery of the fastener, there are mating surfaces and misalignment surfaces spaced apart, and the mating trajectory formed by the mating surfaces is larger than the misalignment trajectory formed by the misalignment surfaces.

[0019] The beneficial effects of this invention are as follows: This invention cleverly utilizes the assembly of the cover and handle to facilitate the disassembly and installation of the steel cover and its accessories, providing a basis for cleaning the steel cover and ensuring that it can be disassembled, maintained, and cleaned in the future.

[0020] The disassembly method in this invention eliminates the need for holes in the steel cover and for securing it with nuts or bolts, thus avoiding the aforementioned problems. This patent primarily utilizes the faceplate and cantilever on the steel cover, designing structural features that allow them to interlock, achieving the purpose of detachable steel cover components. This design avoids the problems found in existing products. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0023] See attached document Figure 1-15 As shown, the pressure cooker lid assembly in this embodiment includes a steel lid 100, which is partially recessed to form an assembly base 110. Furthermore, a handle 200 is mounted on the assembly base 110. A steel lid fitting 300 is provided on the side of the handle 200 near the steel lid 100. Either the steel lid fitting 300 or the assembly base 110 forms an assembly part 400, and the other forms an assembly locking groove 500. The assembly part 400 and the assembly locking groove 500 are assembled or disassembled within a set range within the assembly base by applying external force, touching a button, or rotating, thereby realizing the installation and removal of the steel lid.

[0024] In this embodiment, the steel cover 100 and the face cover 600 are assembled and connected to form an integral unit. Therefore, it is only necessary to assemble one of the head cover components with other components to realize the assembly of the face cover or the steel cover on the head cover. The face cover 600 can be connected to the steel cover by means of buckles, such as one having a hole and the other having a slot, so that they can be assembled. Both are circular plate structures and are generally placed in the ring structure of the head cover.

[0025] Furthermore, in this embodiment, a stepped gap is formed between the mounting base 110 and the handle 200. This assembly method provides an assembly gap for easy assembly; during rotation, friction is low, facilitating rotation.

[0026] Specifically, this invention provides three assembly methods to facilitate the assembly of the steel cover, as follows: See attached document Figure 1-4 As shown, it provides the first assembly method, which is mainly based on forced force.

[0027] In this embodiment, the assembly part 400 with a force-bearing surface is formed by a partial protrusion in the assembly base 110, and the assembly part 400 is recessed inward in the circumferential direction to form a snap-fit ​​groove 410. The handle 200 is formed with the assembly slot 500 that cooperates with it through the slider assembly 510.

[0028] See attached document Figure 3 As shown, to facilitate assembly and disassembly, a first guide surface 420 and a second guide surface 430 are formed on the assembly part 400. The first guide surface 420 and the second guide surface 430 form the assembly guide trajectory and disassembly guide trajectory of the slider assembly 500. In this embodiment, both guide surfaces are arc-shaped structures. One is used for entry from the outside. Therefore, the first guide surface can be a trajectory guiding from the center of the assembly part 400 towards the outer edge, while the second guide surface is a trajectory guiding from the inner center towards the outer edge from within the surface of the locking groove 410. The two guide surfaces are respectively disposed on the upper side of the locking groove 410, and both are located on the two outer surfaces of the side.

[0029] See attached document Figure 4 As shown, to facilitate the sliding of the slider assembly 510 and its limiting during sliding, a guide rail assembly 520 is also included, which is mounted in opposite directions. The slider assembly 510 moves within a set range of the guide rail assembly 520, and the projection surface formed by the mounting base 110 covers the projection surface formed by the guide rail assembly 520. In this embodiment, the mounting base 110 forms a large mounting surface, which allows the guide rail assembly 520 to form a smaller range of motion on the mounting surface. The slider assembly 510 moves within this range of motion to achieve assembly. Specifically, whether during disassembly or assembly, the external force causes the symmetrically arranged slider assemblies 510 to move outward in opposite directions, forming a larger clamping space to facilitate the insertion or removal of the snap-fit ​​groove 410. After insertion or removal, the two slider assemblies 510 move inward again, forming a smaller clamping space.

[0030] In this embodiment, the slider assembly 510 is formed by stacking several sliding plates, with the top slider extending inward to form a limiting groove that matches the snap-fit ​​groove 410. This method is chosen because the limiting cavity is ultimately engaged with the snap-fit ​​groove for assembly. The use of stacked sliding plates for the slider assembly serves two purposes: firstly, the smooth surface of the sliding plates reduces friction during assembly; secondly, the stacked arrangement allows for height adjustment and also adjusts the spacing between the slider assemblies at different heights to accommodate the snap-fit.

[0031] In this embodiment, the sliders at the limiting grooves are arranged facing each other, with their ends being arc-shaped. The symmetrically arranged sliders form a bracket-shaped limiting groove. Consequently, the top of the slider assembly cannot move up and down due to the limiting mechanism, and can only move horizontally for control.

[0032] The guide rail assembly forms a sliding groove along its length, and then the slider assembly is assembled into the sliding groove. Furthermore, limit parts are provided on both sides of the sliding groove to prevent the slider assembly from sliding too far beyond its original range.

[0033] In this embodiment, the assembly part 400 can also be disposed inside the cover 600, and then the cover 600 and the steel cover 100 can be inserted into the slot.

[0034] When in use, when the two are assembled in the direction of proximity, the buckle on the steel cover 100 forms the assembly part 400, and at the same time, the two guide surfaces on it form a guide structure, which will force the slider assembly 510 to move outward. After reaching a certain position, the slider assembly 510 will enter the buckle groove (i.e., the locking groove 410), thereby achieving the purpose of locking the steel cover assembly. Similarly, when disassembling the steel cover assembly, the guide structure (i.e., the second guide surface 430) on the steel cover assembly buckle will force the slider assembly 510 to move outward. Then, when the buckle groove 410 disengages from the slider assembly 510, the purpose of disassembling the steel cover assembly is achieved.

[0035] The disassembly and assembly in this embodiment requires no other operation; the steel cover can be removed simply by pulling it outwards. Similarly, the assembly in this embodiment requires only aligning the parts and pressing them inwards to assemble the steel cover assembly.

[0036] See attached document Figure 5-11 As shown, it offers a second assembly method, which is mainly based on button assembly.

[0037] See attached document Figure 5-11 As shown, in this embodiment, the assembly part 400 is a button 440 disposed within the assembly base 110. The button 440 has a recessed side forming a locking part 441. The handle 200 is provided with a sliding groove 530 and a latch 540 that moves along the sliding groove 530. The latch 540 matches the locking part 441. In this embodiment, when the handle and the assembly part 400 are close together, the latch is pressed first, causing the latch 540 to move along the sliding groove 530. When the button is assembled close to the latch, the latch passes through and engages with the locking part 441, achieving locking. During disassembly, pressing the button on the latch 540 causes it to retract, applying force to separate the handle and the assembly part, completing the disassembly.

[0038] In this embodiment, the assembly part 400 can be set on the steel cover 100 or the face cover 600. The steel cover 100 and the face cover 600 are connected by a snap-fit ​​method. If one of them is removed, the other will also be removed.

[0039] In this embodiment, a pusher structure 541 is formed on the buckle to increase the pressure on the watch. The purpose is to facilitate the application of force to control its sliding. For example, when force is applied downward to the pusher structure 541, the spring is compressed, causing the buckle 540 to move closer to or away from the locking part 441, so that the locking part 441 is locked or disengaged, thereby achieving locking or unlocking.

[0040] To achieve a good assembly method and aesthetically pleasing assembly, the surface of the steel cover 100 protrudes to form a slide rail surface 120 facing the slide groove, and the projected surface of the button 440 covers the slide rail surface 120. In this embodiment, the slide rail surface 120 is specifically a sloping structure and is set downwards towards the slide groove, thereby guiding the button 440 to move downwards and assisting in locking.

[0041] Referring to the accompanying drawings, in this embodiment, the slide groove 530 is perpendicular to the slide rail surface 120. A positioning element 531 is provided on the slide groove 530. The latch 540 is partially hollowed out to form a sliding cavity, and the positioning element 531 is located within the sliding cavity. In this embodiment, the slide groove 530 is specifically an L-shaped structure, with its transverse side perpendicular to the slide rail surface 120, while the vertical side with the latch 540 is parallel to the slide rail surface 120. There are two positioning elements 532, which form a limiting cavity within the hollowed-out structure, allowing the slide groove 530 to move the hollowed-out structure within the limiting cavity to achieve locking and unlocking. A return spring 560 is provided within the hollowed-out structure.

[0042] In this embodiment, the return spring 560 and the positioning member 531 cooperate to limit the movement of the latch 540 within the slide groove 530, facilitating precise locking. For example, the return spring 560 restricts the horizontal movement distance of the latch, while the positioning member 531 assists in limiting the horizontal movement distance.

[0043] In this embodiment, a button and handle structure are used to lock and unlock the device, which takes up little space, requires little external force, and has an ingenious structure.

[0044] In this embodiment, an assembly groove 210 is provided on the inner surface of the handle 200. A through hole 211 for the latch 540 to pass through is provided on one side of the assembly groove 210, and a through cavity with openings at both ends is formed on the side of the assembly groove to form a limiting cavity 220, so that the slide 530 is located in the limiting cavity 220, thus preventing the slide 530 from moving around randomly.

[0045] The assembly and usage process in this embodiment is as follows: First, the mounting groove 210, through hole 211, and limiting cavity 220 on the handle 200 are directly fixed to the inner surface of the handle 200 near the steel cover 100. The slide 530 is fitted into the two positioning parts by the positioning part 541 and is limited by the limiting cavity 220. As a result, the assembly space is limited. At this time, limits are formed on the horizontal X-axis and Y-axis respectively, which not only restricts the assembly of the slide 530, but also provides a limiting function for the movement of the button 440.

[0046] Secondly, in order to ensure the assembly of the handle surface, the slide groove 530 is set as an L-shaped structure, so that its horizontal X-axis direction is assembled in the limiting groove 220, while the Y-axis is set next to the slide rail surface 120 and parallel to it. At this time, the Y-axis direction of the L-shaped structure is set close to the through hole 211, so that the latch 540 on the L-shaped structure can be easily inserted into the through hole 211, which prepares the foundation for its subsequent locking of the locking part 441.

[0047] Furthermore, in use, the latch 540 has an L-shaped structure, with a handle structure 541 on one side and a slide groove 530 on this side. A return spring 560 is located near the handle structure 541. Pressing the handle structure 541 compresses the return spring 560, causing the entire latch 540 to move along the slide groove 530 along the horizontal X-axis. Meanwhile, the other side of the latch 540 forms a locking part. When the horizontal movement reaches a set position, the applied force stops, and the released return spring 560 returns to its original position, causing the entire latch 540 to retract along the X-axis. The locking part then enters the through hole 211 in the assembly groove 210, matching the button 440 inside, thus locking the locking part 441. In this embodiment, the button 440 is fixedly mounted on the assembly part 400. By adjusting the Y-axis distance between the assembly part 400 and the handle 200, the button can be moved closer to or further away from the locking part and the through hole for easier locking. During the later unlocking process, force is applied to the handle structure to make the entire latch 540 move horizontally, disengage from the through hole 211, and then the button is pressed to unlock. Force is applied to separate the assembly and the handle to complete the unlocking.

[0048] In this embodiment, a button locking method is selected, which makes the operation clear. When disassembling the steel cover assembly, simply press the button to achieve the purpose of disassembling the steel cover assembly; the steel cover assembly cannot be disassembled without pressing the button.

[0049] In this embodiment, although the locking method of the latch and locking part is relatively conventional, in this invention, by utilizing the movement of the handle and the assembly part, the fixed button 440 is first brought closer to the assembly groove 210, so that the button 440 enters the assembly groove 210. Then, its position in the assembly groove 210 is adjusted so that it is completely inserted into the assembly groove 210. At this time, by controlling the push handle structure 541, the latch passes through the through hole 211 and enters the assembly groove 210, thus achieving complete locking of the button. The whole process is simple to operate, easier to implement, and the structure provides good protection after locking.

[0050] See attached document Figure 12-15 As shown, this embodiment also provides a rotary assembly method, as detailed below: In this embodiment, the assembly part 400 is a fastener 450 disposed on the handle 200. The assembly base 110 has a receiving cavity and an assembly locking groove 500 on the receiving cavity. The fastener 450 rotates along the receiving cavity, causing it to be misaligned or aligned with the assembly locking groove 500, thereby achieving locking or unlocking. The assembly method in this embodiment is time-saving and labor-saving, as unlocking and locking can be achieved directly by rotation, making it more convenient to use. Furthermore, the fastener can be hidden under the handle, making the entire structure relatively concealed and the design reasonable.

[0051] In this embodiment, a contact surface 451 and a misalignment surface 452 are provided at intervals along the outer periphery of the fastener 450. The contact trajectory formed by the contact surface 451 is larger than the misalignment trajectory formed by the misalignment surface 452. Similarly, referring to the accompanying drawings, a third guide surface 460 and an assembly surface 470 are formed circumferentially around the assembly part 400, and the third guide surface 460 and the assembly surface 470 are provided at intervals. In this embodiment, the guide surface is used to guide the assembly part into the assembly slot 500, while the assembly surface is fully engaged with the rotating part during contact; at this time, it is not locked, but simply assembled. Locking only occurs when the assembly surface is misaligned with the rotating part.

[0052] Specifically, of the third guide surface 460 and the assembly surface 470, one is an arc surface formed by an arc structure, and the other is a square surface composed of straight lines. Preferably, the guide surface is an arc structure. Utilizing the arc structure and the square structure, the arc structure has less friction and is easier to enter. Then, the inner surface of the assembly slot is provided with a contact surface corresponding to the assembly surface of the square structure for assembly during entry.

[0053] In one embodiment, the third guide surface 460 and the assembly surface 470 respectively form a guide trajectory and an assembly trajectory, wherein the length of the assembly trajectory is greater than the length of the guide trajectory. In this embodiment, the assembly trajectory is long, meaning the trajectory of the assembly part entering the receiving cavity is long, while the guide surface is short, resulting in more contact surfaces for the assembly. Specifically, it forms a rectangular structure, with the guide surface forming the width direction and the assembly surface forming the length direction.

[0054] In this embodiment, the fastener 450 is a cuboid with arc-shaped structures on both sides in the width direction. A smaller cuboid forming a rotating part 453 is provided on the cuboid, and the two are connected by a pivot, allowing the rotating part 453 to rotate along the assembly part 400. The assembly locking groove 500 is an annular structure, with a diameter greater than the width of the assembly part and greater than or equal to the length of the cuboid, allowing the assembly part 400 to rotate within the receiving cavity, with a gap between the assembly part 400 and the receiving cavity. However, the arrangement of the assembly locking groove and the rotating part 453 limits the overall rotation to a certain range. In this case, the assembly groove is a groove with a large length and a small width, while the width of the rotating part 450 is greater than the width of the smaller groove, but its length is greater than its width, thus it will be locked after rotating a certain angle.

[0055] In this embodiment, in the assembly part 400, the third guide surface 460 corresponds to the misalignment surface 452, both of which can be selected as arc-shaped structures, while the assembly surface 470 corresponds to the mating surface 451, which can be selected as a rectangular or other planar structure. Furthermore, in the assembly groove 500, when its arc shape matches a rectangular or other planar shape, the steel cover and the steel cover assembly are unlocked, while when it is rotated and misaligned, it is locked.

[0056] In one embodiment, the assembly slot 500 is an annular structure with a partial circumferential protrusion forming the assembly groove 550. In this embodiment, the annular structure forms a closed cavity. However, the cavity can also be a non-circular annular structure formed by a cuboid or other similar structure. The closed cavity formed by the annular structure is located at a relatively low position, allowing the annular structure to limit the assembly of the assembly part within the lower closed cavity. If the assembly is not yet firmly secured, a misaligned locking mechanism using a rotating part ensures a secure connection. The overall arc shape of the annular structure minimizes friction when the assembly part contacts the cavity and the assembly groove. Specifically, the assembly groove 550 is composed of two symmetrical arcs to facilitate clamping at the top.

[0057] In one embodiment, to achieve a good limiting effect, the protrusion has a symmetrical structure, and the trajectory formed by the protrusion is at least one-sixth to one-quarter of the annular circumference. That is, in this embodiment, the clamping length of the assembly groove 550 is less than half of the annular shape, thus allowing for a large range of motion. However, due to the protrusion, it can limit the rotation trajectory of the rotating part, allowing it to switch between a misaligned jammed state and a misaligned removal state.

[0058] In one embodiment, the assembly part 400 is located above the rotating part 453, and the projection formed by the assembly part 400 covers the projection formed by the rotating part 453. In this embodiment, the assembly part is not only long, but also equal to or greater than the width of the assembly groove 550 in the width direction, ensuring that the rotating part is only a part of the assembly part, and the assembly part 400 mates with the receiving cavity, but it is only fitted together, while the rotation of the smaller rotating part makes the assembly more secure.

[0059] In this embodiment, the assembly and the rotating part are superimposed structures, as are the receiving cavity and the assembly groove. Thus, the height of the receiving cavity is equal to the height of the assembly, and the height of the assembly groove is equal to the height of the rotating part, achieving equal-height assembly.

[0060] In this embodiment, the pot lid assembly can only be disassembled and assembled by rotating it to a specific angle, which ensures that the angle is unique and the reliability is high.

[0061] In this embodiment, the core is the disassembly of the head cover assembly, specifically including the steel cover 100 and the face cover 600 assembled using assembly rings and bolts. The steel cover and face cover need to be drilled on the same side, which seriously affects their airtightness. However, in this embodiment, no drilling is required, and they are directly assembled, which not only has good airtightness, but is also easy to disassemble, assemble and clean, making it more hygienic to use.

The assembly base has a local protrusion to form an assembly part with a force-bearing surface. The assembly part is recessed inward in the circumferential direction to form a snap-fit ​​groove. The handle has an assembly locking groove that cooperates with it through a slider assembly. The slider assembly is composed of several stacked slides, with the top slide extending inward to form an assembly slot that matches the buckle slot. The sliding plates at the assembly slot are arranged facing each other, with their ends being arc-shaped. The symmetrically arranged sliding plates form a bracket-shaped assembly slot. The assembly part is formed with a first guide surface and a second guide surface, which form the assembly guide trajectory and disassembly guide trajectory of the slider assembly. It also includes opposing guide rail assemblies, the slider assembly moves within a set range of the guide rail assembly, and the projection surface formed by the mounting base covers the projection surface formed by the guide rail assembly; When the assembly part and the slider assembly are assembled in the direction of proximity, the first guide surface and the second guide surface form a guide structure, which forces the slider assembly to move outward and enter the snap-fit ​​groove, thereby achieving the purpose of snapping the steel cover. When the steel cover is pulled outward, the guide structure on the steel cover buckle forces the slider assembly to move outward, thereby disengaging the buckle from the slider assembly and achieving the purpose of removing the steel cover.

2. The pressure cooker cap assembly according to claim 1, characterized in that, A stepped gap is formed between the mounting base and the handle.
