Description

Technical Field

[0001] This utility model relates to the field of pot lids, and in particular to a pot lid with a detachable top bead. Background Technology

[0002] Chinese Patent CN213155447U discloses a pot lid with a top bead, including a lid body and a top bead detachably fixed to the upper end of the lid body. The top bead includes a gripping block located at the upper end of the lid body, a telescopic rod elastically interlocking with the gripping block, a spring located inside the gripping block to drive the telescopic rod to retract, a limiting groove perpendicular to the telescopic rod provided on the outer ring wall of the telescopic rod, and a limiting block interlocking with the limiting groove. When the telescopic rod interlocks with the lid body, the limiting block interlocks with the limiting groove to limit the retraction of the telescopic rod. The telescopic rod includes a pressing block located at the upper end and a movable rod with a diameter smaller than the pressing block located at the lower end. The upper end of the gripping block has a recessed relief groove for the pressing block to rise and fall, and the bottom of the relief groove has a relief hole for the movable rod to pass through. The spring is sleeved on the movable rod and located in the relief groove.

[0003] In the above structure, when the top ball needs to be installed on the cover, firstly, the movable rod with a spring sleeve on its outer wall needs to be inserted into the clearance hole. Then, press the pressing block set on the top of the movable rod so that the lower end of the movable rod passes through to the bottom of the gripping block and engages with the through hole of the cover. Then, install the limiting block until the movable rod passes through the cover. Finally, release the pressing block so that the spring drives the movable rod to rise, thereby making the surface of the limiting block abut against the bottom of the limiting groove in the cover, thus realizing the installation between the top ball and the cover. When the top ball needs to be removed from the cover, the pressing block needs to be pressed to make the limiting block disengage from the limiting groove, and then the limiting block needs to be removed from the movable rod before the top ball can be removed from the cover.

[0004] In the above structure, each time the top ball is disassembled or reassembled, the limiting block must be installed onto the movable rod or removed from the movable rod, making the removal process of the top ball troublesome and time-consuming. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies where the limiting block must be installed on or removed from the movable rod each time the top ball is disassembled, resulting in a troublesome and time-consuming process for removing the top ball. It provides a pot lid with a detachable top ball that is convenient and time-saving to install and remove.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A pot lid with a detachable top ball includes a lid body, a top ball, and a detachable structure disposed between the top ball and the lid body. The detachable structure includes a magnetic attraction structure disposed between the lid body and the top ball, and a desorption structure disposed on the top ball for separating the lid body from the top ball.

[0008] Using the above solution, the magnetic attraction structure between the top bead and the cover body enables the installation of the top bead and the cover body, thus facilitating their installation. The desorption structure on the top bead releases the magnetic attraction between the top bead and the cover body when the top bead needs to be removed from the cover body, thus making it easier to remove the top bead from the cover body. Through the magnetic attraction structure and the desorption structure, the installation and removal of the top bead and the cover body can be achieved, making the installation and removal of the top bead and the cover body more convenient and faster.

[0009] Preferably, the magnetic attraction structure includes a first adsorption element disposed at the bottom of the top bead and a second adsorption element disposed on the top surface of the cover. The first adsorption element and the second adsorption element are both magnets, or one is a magnet and the other is a metal block that can be attracted by a magnet.

[0010] Using the above scheme, the first adsorption component on the top bead can adsorb onto the second adsorption component on the cover when the top bead is installed onto the cover, thereby realizing the installation between the top bead and the cover.

[0011] Preferably, the desorption component includes a pressing top that moves up and down on the top bead. A limiting structure is provided between the pressing top and the top bead to restrict the pressing top from disengaging from the upper and lower end faces of the top bead. The lower end of the pressing top can be fully retracted or partially extended to the lower end of the top bead.

[0012] Using the above solution, when the magnetic attraction between the cover and the top bead needs to be de-attracted, the pressing top piece can be driven to move closer to the cover, so that the lower end of the pressing top piece is fully retracted or partially extended to the lower end of the top bead. When the pressing top piece moves closer to the cover, it will push the cover downward, thereby causing the magnetic attraction on the cover to gradually move away from the magnetic attraction on the top bead, reducing the attraction between the magnetic attraction on both, thus realizing the disassembly of the top bead and the cover.

[0013] Preferably, the pressing top part is in the shape of a blind tube with the opening facing downwards. The side wall of the pressing top part is provided with a guide groove that connects to the bottom. The top of the top bead is provided with a slot that allows the pressing top part to be raised and lowered. The lower end of the pressing top part extends outwards horizontally with a limiting block. The top of the slot is provided with a limiting ring that abuts against the limiting block. The top bead is provided with a guide block that is integrally protruded from the inner wall of the slot and cooperates with the guide groove.

[0014] Using the above scheme, the slot on the top ball allows the top ball to move within it, while the limiting block on the pressing top piece can abut against the limiting ring in the slot when the pressing top piece moves upward, thereby limiting the pressing top piece to continue moving upward and reducing the probability of the pressing top piece coming out of the slot. The guide block on the inner wall of the slot can guide the pressing top piece to move within the guide groove of the pressing top piece when it moves, thereby guiding the movement of the pressing top piece and preventing the pressing top piece from deflecting during movement.

[0015] Preferably, an elastic element is provided between the pressing top and the guide block to drive the pressing top in an upward state.

[0016] Using the above solution, the elastic element set between the pressing top and the guide block can drive the pressing top to automatically reset upward after it moves downward, thus facilitating the subsequent use of the pressing top.

[0017] Preferably, the first adsorption element is located on the upper end face of the guide block and is pressed against the upper end face of the guide block by the elastic element.

[0018] By adopting the above scheme, the first adsorption component is placed on the upper end face of the guide block, and the first adsorption component is pressed against the upper end face of the guide block by the elastic component, thereby making the installation of the first adsorption component more convenient.

[0019] Preferably, the bottom of the top bead is recessed upward at the lower end of the limiting block to form a slot for the insertion of the second adsorption element.

[0020] Using the above solution, the slot at the bottom of the top bead allows the second adsorption component to be inserted, thereby increasing the adsorption area between the second and first adsorption components and reducing the probability of the top bead detaching from the lid. At the same time, inserting the second adsorption component into the slot at the bottom of the top bead can also improve the overall aesthetics of the lid after the top bead is installed on the lid.

[0021] Preferably, the bottom of the second adsorption element is fixed with a bolt, and the center of the cover has a through hole through which the bolt can pass. A nut is screwed onto the bolt to lock the second adsorption element onto the cover.

[0022] Using the above scheme, the bolt located at the bottom of the second adsorption component can cooperate with the nut after passing through the through hole in the center of the cover, thereby achieving the fixation between the second adsorption component and the cover.

[0023] This utility model, by adopting the above technical solutions, has significant technical effects: the magnetic attraction structure set between the top bead and the cover body enables the installation of the top bead and the cover body, thus facilitating the installation of the top bead and the cover body; while the desorption structure set on the top bead can release the attraction effect between the top bead and the magnetic structure on the cover body when the top bead needs to be removed from the cover body, thus facilitating the removal of the top bead from the cover body. Through the set magnetic attraction structure and desorption structure, the assembly and disassembly of the top bead and the cover body can be realized, making the assembly and disassembly of the top bead and the cover body more convenient and quick.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0031] Example

[0032] A pot lid with a removable top bead, see reference. Figures 1-3 The device includes a cover 1, a top bead 2, and a detachable structure disposed between the top bead 2 and the cover 1. The detachable structure includes a magnetic attraction structure disposed between the cover 1 and the top bead 2 and a desorption structure disposed on the top bead 2 for separating the cover 1 from the top bead 2. The magnetic attraction structure includes a first adsorption element disposed at the bottom of the top bead 2 and a second adsorption element disposed on the top surface of the cover 1. The first adsorption element and the second adsorption element are both magnets 3 or one is a magnet 3 and the other is a metal block 4 that can be attracted by the magnet 3. In this embodiment, the first adsorption element disposed at the bottom of the top bead 2 is a magnet 3, and the second adsorption element disposed at the top of the cover 1 is a metal block 4 that can be attracted by the magnet 3. The desorption component includes a pressing top element 5 that moves up and down on the top bead 2. A limiting structure is disposed between the pressing top element 5 and the top bead 2 to restrict the pressing top element 5 from coming off the upper and lower end surfaces of the top bead 2. The lower end of the pressing top element 5 can be fully retracted or partially extended to the lower end of the top bead 2.

[0033] refer to Figures 2-5 The pressing top part 5 is in the shape of a blind tube with the opening facing downward. The side wall of the pressing top part 5 is provided with a guide groove 6 that connects to the bottom. The top of the top bead 2 is provided with a slot 7 that allows the pressing top part 5 to be raised and lowered. The lower end of the pressing top part 5 extends outward horizontally with a limiting block 8. The top of the slot 7 is provided with a limiting ring 9 that abuts against the limiting block 8. The top bead 2 is provided with a guide block 10 that is integrally protruded on the inner wall of the slot 7 and cooperates with the guide groove 6.

[0034] An elastic element is provided between the pressing top 5 and the guide block 10 to drive the pressing top 5 to be in an upward state. In this embodiment, the elastic element is a spring 11. The first adsorption element is located on the upper end surface of the guide block 10 and is pressed by the elastic element to abut against the upper end surface of the guide block 10. The bottom of the top bead 2 is recessed upward at the lower end of the limiting block 8 to form a slot 12 for the second adsorption element to be inserted.

[0035] The bottom of the second adsorption component is fixed with a bolt 13, and the center of the cover 1 is provided with a through hole 14 through which the bolt 13 can pass. A nut 15 is screwed onto the bolt 13 to lock the second adsorption component onto the cover 1.

[0036] Specific disassembly and assembly process: When the top bead 2 needs to be installed on the cover 1, firstly, align the slot 12 on the top of the top bead 2 with the metal block 4 on the cover 1. Then, move the slot 12 downwards so that the metal block 4 is inserted into the slot 12. As the metal block 4 is inserted into the slot 12, the magnet 3 on the top bead 2 will gradually approach the metal block 4 on the cover 1. When the metal block 4 is fully inserted into the slot 12, the metal block 4 will attract the magnet 3 on the top bead 2, thus realizing the installation between the top bead 2 and the cover 1. When the top bead 2 needs to be removed from the cover 1, firstly, press the top bead 2 so that the pressing top bead 2 pushes the metal block 4. When the metal block 4 is pushed by the top bead 2, the metal block 4 will drive the cover 1 to move downwards. At this time, the metal block 4 will gradually move away from the magnet 3 on the top bead 2. At this time, the attraction between the metal block 4 and the magnet 3 will gradually decrease. When the attraction between the metal block 4 and the magnet 3 decreases, the top bead 2 can be removed from the cover 1.
