The utility model discloses do not do specifically and restrict to the form that lining lid buckle 110 and face lid buckle 210 set up arc-shaped buckling face, it contains but not limited to the condition that the following embodiment lists:

example 1: as shown in fig. 3 (for convenience, the structures of the first arc-shaped fastening surface 111 and the second arc-shaped fastening surface 211 are shown, and the two are shown separately), the first arc-shaped fastening surface 111 protruding outwards is provided on the lining cover fastener 110, the second arc-shaped fastening surface 211 recessed inwards is provided on the surface cover fastener 210, and at least part of the first arc-shaped fastening surface 111 and part of the second arc-shaped fastening surface 211 form a concave-convex fit, so that after the lining cover 100 and the surface cover 200 are assembled, the lining cover fastener 110 and the surface cover fastener 210 are not separated, and the concave-convex fit can reduce the gap between the lining cover 100 and the surface cover 200, so that the lining cover 100 and the surface cover 200 can be tightly attached together, which is the best fit.

The arc curvatures of the first arc-shaped fastening surface 111 and the second arc-shaped fastening surface 211 are not necessarily equal, and the curvature of the second arc-shaped fastening surface 211 on the surface cover buckle 210 can be smaller than the curvature of the first arc-shaped fastening surface 111 on the lining cover buckle 110, so that the lining cover buckle 110 and the surface cover buckle 210 can be well fastened, and the contact area between the lining cover buckle 110 and the surface cover buckle 210 can be reduced.

Example 2: the lining cover buckle 110 is provided with a convex first arc-shaped buckling surface 111, the surface cover buckle 210 is provided with a convex second arc-shaped buckling surface 211, the first arc-shaped buckling surface 111 and the second arc-shaped buckling surface 211 are abutted, namely, the lining cover buckle 110 and the surface cover buckle 210 are both convex, the lining cover buckle 110 and the surface cover buckle 210 are similar to the existing lining cover buckle 110 and surface cover buckle 210 in buckling mode, the difference lies in that after the lining cover 100 and the surface cover 200 are buckled, the lining cover buckle 110 and the surface cover buckle 210 are abutted through the first arc-shaped buckling surface 111 and the second arc-shaped buckling surface 211 to realize buckling, and therefore the purpose that the contact area of the lining cover buckle 110 and the surface cover buckle 210 is reduced is achieved.

On the basis of the above embodiment, the arc-shaped fastening surface may be made into a hemispherical surface, so that when the liner cover fastener 110 and the face cover fastener 210 are fastened, the two form a point contact, thereby greatly reducing the friction force between the liner cover fastener 110 and the face cover fastener 210 when the liner cover 100 needs to be detached.

The arc-shaped fastening surface can be a semi-cylindrical surface, the axial directions of the arc-shaped fastening surfaces on the lining cover buckle 110 and the surface cover buckle 210 are parallel, when the lining cover buckle 110 and the surface cover buckle 210 are buckled, the lining cover buckle 110 and the surface cover buckle 210 form line contact, and compared with the existing surface contact, the friction force between the lining cover buckle 110 and the surface cover buckle 210 when the lining cover 100 is detached from the surface cover 200 can be effectively reduced.

As shown in fig. 4 and 5, since the surface cover buckle 210 and/or the lining cover buckle 110 employ the arc-shaped buckling surface, in order to ensure that the surface cover buckle 210 and the lining cover buckle 110 can be buckled when the surface cover 200 is buckled with the lining cover 100, the surface cover 200 is provided with the limiting ribs 220 at two circumferential sides of the surface cover buckle 210, the limiting ribs 220 limit the movement track of the lining cover buckle 110 when the surface cover 200 is buckled with the lining cover 100, the surface cover buckle 210 and the lining cover buckle 110 cannot be dislocated when buckled, and the surface cover buckle 210 and the lining cover buckle 110 can be buckled in place. Of course, in order to achieve the above purpose, the lining cover 100 may be further provided with the limiting ribs 220 at both sides of the lining cover buckle 110 in the circumferential direction.

Because the arc-shaped fastening surface of the surface cover fastener 210 and/or the lining cover fastener 110 is the contact surface after the surface cover 200 is fastened with the lining cover 100, and at least one of the surface cover fastener 210 and the lining cover fastener 110 is convex, in the process of fastening the surface cover 200 with the lining cover 100, in order to facilitate the fastening of the surface cover fastener 210 and the lining cover fastener 110, a guide inclined surface 230 is arranged below the surface cover fastener 210 of the surface cover 200 and/or above the lining cover fastener 110 of the lining cover 100, as shown in fig. 5, a plurality of inclined guide ribs can form the guide inclined surface 230, or the surface cover fastener 210 and the lining cover fastener 110 can be directly made into a hemispherical shape or a semi-cylindrical shape, thereby realizing both the arc-shaped fastening surface and the arc-shaped guide inclined surface 230.

On the basis of the above embodiment, the surrounding edge 120 extending outward is disposed on the periphery of the liner cover 100, the surrounding edge 120 is favorable for eliminating the gap between the liner cover 100 and the surface cover 200, the edge is provided with the arc rib 130 extending upward, the arc rib 130 can have better elasticity, so as to generate slight elastic deformation when the liner cover 100 is assembled and disassembled, and the liner cover buckle 110 is disposed on the outer side of the arc rib 130, because in actual production, in order to reduce the weight of the liner cover 100, the edge thickness of the liner cover 100 is often thinner, and the liner cover 100 is provided with criss-cross support ribs, so that it is difficult to dispose the liner cover buckle 110 on the sidewall of the liner cover 100, and the problem of disposing the liner cover buckle 110 is solved by using the surrounding edge 120 and the arc rib 130. Accordingly, the face cap 200 includes a side wall of the face cap 200 disposed along the circumferential side of the liner cap 100 to facilitate the sidewall engagement of the liner cap 100, reducing or eliminating the gap between the face cap 200 and the liner cap 100, and the face cap latch 210 is disposed inside the side wall of the face cap 200.

Further, as shown in fig. 3, the lower portion of the side wall of the surface cover 200 overlaps the outer peripheral surface of the surrounding edge 120, that is, the surface cover 200 and the lining cover 100 are connected to the pot body in a gap, which is the same as the direction of the force applied to the surface cover when the surface cover 200 and the lining cover 100 are disassembled, and when the surface cover and the lining cover are separated, the force can be directly applied to the bottom of the side wall of the surface cover for disassembly without using tools.

When the installation is needed, the lining cover 100 is pushed into the face cover 200 from bottom to top, at the moment, the bayonet of the lining cover 100 also slides over the face cover buckle 210 from bottom to top, the arc-shaped buckling surface of the lining cover buckle 110 is positioned above the arc-shaped buckling surface of the face cover buckle 210, so that the installation of the face cover 200 and the lining cover 100 is completed, in the process, the face cover 200 or the lining cover 100 can slightly deform, but because the face cover 200 or the lining cover 100 is generally made of plastics, the deformation cannot influence the deformation of the face cover 200 or the lining cover 100, and after the installation is completed, the face cover 200 and the lining cover 100 can restore to the original shape. When the lining cover 100 needs to be detached from the surface cover 200, a tool is only needed to be inserted into a gap between the surface cover 200 and the lining cover 100 and then to be pried, or force is applied to the bottom of the side wall of the surface cover 200, because the contact area between the lining cover buckle 110 and the surface cover buckle 210 is reduced compared with the prior art, the friction force generated by the friction force is small, the surface cover 200 and the lining cover 100 can be easily separated, the surface cover 200 cannot be damaged due to the small prying force, and the lining cover buckle 110 or the surface cover buckle 210 cannot be broken.
