[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 6As shown, a fixing structure of a kettle liner cover of the present embodiment comprises a kettle cover shell 1 and a kettle cover liner 2, wherein the kettle cover liner 2 comprises a liner base 21 and a liner connecting section 22 arranged on the liner base 21, the kettle cover shell 1 comprises a top cover 11 and an annular cover edge 12 arranged at the bottom of the top cover 11, the inner side wall of the annular cover edge 12 encloses an assembly cavity 121, the bottom of the annular cover edge 12 is provided with an assembly opening 122 communicating with the assembly cavity 121, the liner connecting section 22 can be assembled into the assembly cavity 121 through the assembly opening 122, and a snap-fit ​​component is provided between the inner side wall of the annular cover edge 12 and the outer side wall of the liner connecting section 22 to enable the two to be connected.

[0031] Specifically, by arranging a snap-fit ​​assembly between the inner wall of the annular cover edge 12 and the outer wall of the lining connecting section 22, when the pot lid lining 2 is assembled with the pot lid shell 1, the lining connecting section 22 is aligned with the opening and assembled into the assembly cavity 121. At this time, the snap-fit ​​assembly can make the annular cover edge 12 and the lining connecting section 22 achieve a snap fit, so that the pot lid lining 2 can be firmly assembled on the pot lid shell 1. The use of this snap-fit ​​connection method greatly simplifies the assembly process and reduces the difficulty of assembly. In addition, since the number of assembly parts and the complexity of assembly are reduced, the production efficiency of the pot lid is improved and the production cost is reduced.

[0032] like Figures 1 to 6 As shown, the clamping assembly of this embodiment includes a clamping protrusion 3 and a clamping groove 4, the clamping protrusion 3 and the clamping groove 4 are arranged correspondingly, the clamping protrusion 3 is arranged on the inner side wall of the annular cover edge 12, and the clamping groove 4 is arranged on the outer side wall of the liner connecting section 22;

[0033] Specifically, when the liner connecting section 22 is inserted into the assembly cavity 121 through the assembly opening 122, the snap-fitting protrusion 3 will snap into the snap-fitting groove 4, thereby locking the pot lid liner 2 in the pot lid housing 1. The snap-fitting protrusion 3 and the snap-fitting groove 4 can be snap-fitted by simply pushing the pot lid liner 2 appropriately. Users or production personnel can complete the assembly of the pot lid without using any special tools, which has the advantages of simple structure and convenient operation.

[0034] Moreover, this design reduces the complexity of manufacturing the pot cover. Compared with using threads, adhesives or other complex fixing parts, the design of the snap-fit ​​protrusion 3 and the snap-fit ​​groove 4 is simpler and easier to manufacture.

[0035] Preferably, the design in which the snap-fitting protrusion 3 is arranged on the inner side wall of the annular cover edge 12 and the snap-fitting groove 4 is arranged on the outer side wall of the lining connecting section 22 can simplify the production difficulty of the pot cover and facilitate the production of the pot cover.

[0036] In other embodiments, the snap-fit ​​protrusion 3 is provided on the outer wall of the liner connecting section 22, and the snap-fit ​​groove 4 is provided on the inner wall of the annular cover edge 12, and a suitable snap-fit ​​component can be selected according to actual needs.

[0037] like Figures 1 to 6 As shown, the engaging protrusion 3 of this embodiment is in a ring shape. The engaging groove 4 is also in a ring shape.

[0038] Specifically, the annular snap-fit ​​protrusion 3 means that the snap-fit ​​protrusion 3 is arranged on the inner wall around the entire annular cover edge 12, and correspondingly, the snap-fit ​​groove 4 acts as an annular groove around the outer wall of the liner connecting section 22. The annular design means that the assembly force can be evenly distributed along the entire connecting section, thereby reducing the pressure on any single point and reducing wear.

[0039] In addition, annular snap-fit ​​structures generally provide better sealing performance because they can form a continuous closed ring across the entire joint surface, thereby preventing moisture and contaminants from entering the interior of the lid.

[0040] When the liner is inserted into the assembly cavity, the annular design does not require a lot of effort to align the snap-fit ​​protrusion 3 and can naturally guide the snap-fit ​​groove 4 into place, thereby reducing the complexity of assembly.

[0041] Furthermore, the annular snap-fitting projections and recesses also generally increase the overall strength and stability of the structure, as the forces are evenly distributed over a larger area, thereby reducing the risk of local stress concentrations.

[0042] Preferably, the outer wall of the liner connecting section 22 of the present embodiment is close to or against the inner wall of the annular cover edge 12 . This design can further enhance the stability and sealing performance between the liner connecting section 22 and the annular cover edge 12 .

[0043] Furthermore, if the kettle vibrates during use, the close fit between the liner connecting section 22 and the annular cover edge 12 can reduce the noise generated by the shaking of the liner in the kettle cover.

[0044] like Figures 1 to 6 As shown, a guide assembly is also provided on the top of the lining connecting section 22 of this embodiment to facilitate the assembly of the lining connecting section 22 into the assembly cavity 121 , and the guide assembly includes a guide section 5 bent inwardly toward the center direction of the lining base 21 .

[0045] Specifically, the presence of the guide section 5 allows the liner to be guided into the correct position more smoothly when the liner connecting section 22 is assembled into the assembly cavity 121, providing a clear path for the liner connecting section, avoiding misalignment or jamming during the assembly process, speeding up the assembly speed, and improving production efficiency.

[0046] Furthermore, during the assembly process, the guide section 5 also helps prevent the edge of the liner connecting section 22 from scratching or colliding with other components in the pot lid, thereby protecting the internal components from damage.

[0047] like Figures 1 to 6 As shown, the surface of the guide segment 5 of this embodiment has a certain curvature. The guide segment 5 with a certain curvature can reduce friction and resistance during assembly. The curvature can provide a more continuous guiding force, so that the path of the lining connecting segment 22 when assembled into the assembly cavity 121 is smoother and more intuitive, reducing the possibility of misalignment, and allowing the lining connecting segment 22 to be assembled into the assembly cavity 121 more smoothly.

[0048] Furthermore, the curved surface is less likely to scratch or cut the lining or other components than right angles or sharp edges, which can reduce possible damage to the components during assembly.

[0049] In many cases, a structure with a certain curvature is superior to a right-angle structure in terms of mechanical strength, and can better withstand stress without being easily broken.

[0050] like Figures 1 to 6 As shown, the guide segment 5 of this embodiment is made on the lining connection segment 22 by flanging, curling or shrinking processes. Through flanging or curling processes, the edge of the metal will be folded back to form the guide segment 5 on the lining connection segment 22.

[0051] Specifically, the edges after flanging, curling or shrinking will be smoother and have fewer sharp angles, which helps reduce the risk of cuts to operators during use and ensures the guiding function of the guide section 5.

[0052] With such a design, the liner connecting section 22 and the guide section 5 are an integrally formed structure, which can improve the structural strength of the product while reducing material waste, thereby reducing manufacturing costs.

[0053] like Figures 1 to 6 As shown, in this embodiment, a sealing member 6 is sleeved on the outer side wall of the annular cover edge 12 , and a supporting member capable of supporting the bottom of the sealing member 6 is provided on the inner lining base 21 .

[0054] Specifically, the presence of the seal 6 can ensure a good seal between the pot lid and the container, prevent liquid leakage or air entry, and maintain the pressure inside the container and the freshness of the substance.

[0055] The supporting member provides a fixed and supporting platform for the seal, which can absorb the impact force caused by closing and opening the lid, reduce the wear of the seal 6, and extend its service life. In addition, the supporting member also positions the seal 6 to ensure that it is always in the correct position during the closing process of the lid, thereby ensuring the sealing effect.

[0056] like Figures 1 to 6 As shown, the outer diameter of the inner lining seat 21 of the present embodiment is larger than the outer diameter of the inner lining connecting section 22, the top of the inner lining seat 21 has a connecting plane 23, the bottom of the inner lining connecting section 22 is connected to the connecting plane 23, the connecting plane 23 is the supporting member, and the top of the connecting plane 23 can be close to or against the bottom of the seal 6.

[0057] Specifically, the larger outer diameter of the inner lining seat 21 provides a solid supporting foundation for the inner lining connecting section 22, which increases the stability and load-bearing capacity of the entire structure. Moreover, the top of the inner lining seat 21 has a connecting plane 23, which serves as a supporting member so that the bottom of the seal 6 can be close to or against it, which helps to maintain or enhance the sealing of the product. The structure of the inner lining seat 21 itself is used to provide sufficient supporting area for the seal 6, thereby improving the stability and firmness of the connection.

[0058] Specifically, since the connecting plane 23 is located at the top of the liner base 21, this provides a flat contact surface for assembly, making it simpler and more precise to connect the bottom of the liner connecting section 22 thereto. Only abutment is used between the two, which simplifies the overall design and avoids adding additional components to support the seal 6, thereby reducing manufacturing costs and complexity.

[0059] Preferably, the inner lining base 21 of the present embodiment corresponds to covering the seal 6. Furthermore, the supporting member on the inner lining base 21 can cover the bottom of the seal 6, ensuring that the seal 6 will not fall off during use and preventing the bottom of the seal 6 from extending out of the bottom of the kettle lid. When the kettle lining lid is flipped open, the seal 6 will not be seen from the bottom of the kettle lining lid, making the seal 6 and the kettle lid look integrated and more beautiful.

[0060] like Figures 1 to 6 As shown, the snap-fit ​​assembly of this embodiment is located at the intersection of the connecting plane 23 and the lining connecting section 22; that is, the snap-fit ​​groove 4 is arranged at the intersection of the connecting plane 23 and the lining connecting section 22, and the snap-fit ​​protrusion 3 is arranged at the bottom of the inner wall of the annular cover edge 12.

[0061] Specifically, such a design can simplify the manufacturing difficulty of the engaging groove 4 and the engaging protrusion 3 on the pot lid lining and the pot lid shell, and when the engaging protrusion 3 is inserted into the engaging groove 4, the connecting plane 23 will simultaneously abut against the bottom of the annular cover edge 12, so that the lining connecting section 22 cannot continue to be inserted into the assembly cavity 121 in the same direction, thereby preventing the engaging protrusion 3 from continuing to move after being inserted into the engaging groove 4, causing the engaging protrusion 3 to slip out of the engaging groove 4, thereby further playing a positioning role.

[0062] like Figures 1 to 6 As shown, the pot lid lining 2 of this embodiment is made of a metal material with a certain elasticity, such as:

[0063] Flexible stainless steel (such as 304 or 316 stainless steel): Certain stainless steel grades exhibit good flexibility when in thin sheet or filament form and have excellent corrosion resistance.

[0064] Bainitic stainless steel: A type of stainless steel with a high carbon content that has a certain degree of elasticity and hardness and is often used to manufacture elastic parts such as small springs.

[0065] Alloy 42 (Fe-42% Ni): This is a low thermal expansion alloy that also exhibits good elasticity and is often used for elastic parts in precision instruments.

[0066] like Figure 7 As shown, a kettle in this embodiment comprises a kettle body 7, a kettle lining cover and a fixing structure of the kettle lining cover as described in any one of the above items, wherein the kettle cover shell 1 and the kettle cover lining 2 are combined through a snap-fit ​​assembly to form a kettle lining cover, and the kettle lining cover can cover the kettle body 7. A kettle designed in this way can reduce the difficulty of design and production, improve production efficiency and assembly efficiency, and make the kettle more beautiful.

[0067] As described above, multiple implementation methods are provided in combination with specific contents, and the specific implementation of this application is not limited to these descriptions. Any similarity or similarity with the method, structure, etc. of this application, or any technical deduction or replacement made on the premise of the concept of this application, shall be deemed to be within the scope of protection of this application.
