Example (b):

as shown in fig. 1 to 7, a container lid sealing structure of a kitchen appliance, which is assembled on a container lid 1, the container lid 1 has an outer edge 2 on the periphery of the bottom surface, and the container lid 1 is further provided with a ring-shaped wall 3 integrally connected with the bottom surface, characterized in that: the container lid sealing structure includes: the sealing ring component comprises a sealing ring 4 sleeved on the annular wall 3, an upper bracket 5 arranged between the sealing ring 4 and the annular wall 3 and used for limiting the outward turning of the upper part of the sealing ring 4, and a lower bracket 6 used for compressing and limiting the displacement of the sealing ring 4, wherein at least one layer of outward turning edge 401 with the outward turning lower part is formed on the edge of the sealing ring 4, the outer edge of the free end of the outward turning edge 401 is an R-angle sealing part 402, and the inner edge of the outward turning edge is a parting line position 403. The number of the container cover screwing components is at least three, and the container cover screwing components are distributed at the inner side of the outer edge 2 at intervals.

The working principle is as follows: in the technical scheme, the container cover sealing structure is assembled on the container cover 1 and comprises a sealing ring assembly and a container cover screwing assembly; wherein: the sealing ring assembly comprises a sealing ring 4 sleeved on an annular wall 3, an upper bracket 5 arranged between the sealing ring 4 and the annular wall 3 and used for limiting the outward turning of the upper part of the sealing ring 4, and a lower bracket 6 used for compressing and limiting the displacement of the sealing ring 4, as shown in figure 3-5, firstly, the upper bracket 5 is sleeved on the sealing ring 4 and sleeved on the annular wall 3 together, the upper bracket 5 can limit the outward turning of the upper part of the sealing ring 4, and then the sealing property of the sealing ring is ensured, then, the lower bracket 6 is pressed on the sealing ring 4 and fixed with the annular wall 3 mutually to prevent the up-and-down movement of the sealing ring, thereby realizing the fixation of the positions of the upper bracket 5, the sealing ring 4 and the lower bracket 6, being convenient to assemble and disassemble, compared with the prior art that the screwing assembly has insufficient length of mold-out stroke L1 when the rib position 20 is directly arranged on the container cover 1 (as shown in figure 1, the mold can not be manufactured, the upper support 5 is manufactured independently in the technical scheme, so that the screwing component of the container cover 1 can be demoulded, and can also be propped against the sealing ring 4 to be prevented from turning outwards, the structure is simple, and the practicability is high; at least one layer of flanging 401 with the lower part turned outwards is formed on the edge of the sealing ring 4, the flanging 401 turned outwards is pressed by the impulsive force of the stirring liquid to be attached to a container cup more tightly, and further plays a role in sealing, the outer edge of the free end of the flanging 401 is an R-angle sealing part 402, and the inner edge is a parting line position 403. As shown in figures 2-5, when the container cover 1 is buckled on the container cup 19, the R-angle sealing part 402 is abutted to the water sealing contact position of the container cup 19, while the common sealing ring in the prior art is the parting line position, as the parting line position produces burrs which are uneven surfaces, water can not be sealed easily, and the sealing effect is poor, in the technical scheme, the parting line position 403 is designed on the inner edge of the free end of the flanging 401, even if the flanging exists, the sealing problem can be completely worried about because the flanging is not contacted with the water sealing surface of the container cup, the R-angle sealing part 402 is designed at the outer edge of the free end of the outer flanging 401 and is closely contacted with the water sealing surface of the container cup, so that the sealing effect is greatly improved. The container cover sealing structure further comprises a container cover screwing assembly, locking or unlocking between the container cover and the container cup can be achieved through the container cover screwing assembly, operation is convenient, and practicability is high.

Further, it is also contemplated in the present embodiment that the upper bracket 5 has a cross-sectional shape of a gamma, and includes a first annular base 501 transversely disposed, and an annular flange 502 formed at an outer edge of the first annular base 501 and extending downward to surround an upper portion of an outer periphery of the sealing ring 4. The first annular base 501 is located between the sealing ring 4 and the container cover 1, and the annular flange part 502 wraps the upper part of the periphery of the sealing ring 4 to limit the outward turning of the upper part of the sealing ring 4, so that the sealing performance of the sealing ring is guaranteed.

Furthermore, it can be considered in this embodiment that a mold-removing stroke of the screw assembly is formed between the annular wall 3 and the outer rim 2, the width of the mold-removing stroke of the screw assembly is at least 18mm, the length of the mold-removing stroke L2 of the screw assembly is sufficient for the mold to be manufactured, and an annular groove capable of being fastened with the container cup 19 is formed between the annular flange portion 502 and the outer rim 2.

Furthermore, in this embodiment, it is considered that the upper portion of the sealing ring 4 is provided with a ring groove 7 for avoiding the first annular base 501, and at least one ring of annular sealing flange 8 is formed on the upper portions of the sealing ring 4 and the ring groove 7 in a protruding manner. The annular sealing flange 8 plays a role in sealing, prevents residues from entering gaps between the sealing ring 4 and the upper support 5 and between the sealing ring and the container cover 1, and is convenient for subsequent cleaning.

Still further, it is also contemplated in this embodiment that the lower bracket 6 includes an annular connecting portion 601, and a second annular base 602 and a third annular base 603 respectively formed at the upper end and the lower end of the annular connecting portion 601 and extending in opposite directions, where the second annular base 602 and the third annular base 603 are parallel to each other and respectively used for supporting the lower ends of the sealing ring 4 and the annular wall 3 to prevent the sealing ring 4 from moving up and down.

Furthermore, it is also contemplated in this embodiment that the inner side of the sealing ring 4 is convexly formed with at least one ring of annular sealing step 9. The annular sealing step 9 plays a sealing role, prevents residues from entering a gap between the sealing ring 4 and the annular wall 3, and is convenient for subsequent cleaning.

Furthermore, still consider in this embodiment, still be equipped with buckle structure between annular connecting portion 601 and the annular wall 3, buckle structure is including being the even at least three draw-in groove 10 of seting up in the annular wall 3 outside of annular array and being the even at least three and draw-in groove 10 looks adaptation buckle 11 of locating annular connecting portion 601 inboard of annular array, draw-in groove 10, buckle 11 the same and one-to-one setting of quantity. Lower carriage 6 and annular wall 3 through buckle structure connection, simple structure is practical again pleasing to the eye, promoted assembly efficiency and assembly effect between lower carriage 6 and the annular wall 3, the equipment is convenient, and the consumer of being convenient for dismantles, installs by oneself to thoroughly clean each part.
