Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices, systems, apparatuses, and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The cooking utensil generally comprises a pot cover and a pot body, a cooking cavity is formed between the pot cover and the pot body, and a sealing ring 1 is further arranged on the pot cover to hermetically connect the pot cover and the pot body. Referring to fig. 1 to 2, the pot cover includes an inner cover 2, in this embodiment, the cooking appliance is an electric pressure cooker, the inner cover 2 is a steel cover made of stainless steel, and a sealing ring 1 is fixed on the inner cover 2. The cooker cover is also provided with a plurality of fixing pieces 3 for fixing the sealing ring 1. The improved structure of the present application is the cooperation between the fixing member 3, the inner lid 2 and the sealing ring 1, so that other structures on the pot lid that are not related to the improved structure of the present application are not shown and will not be described.

As shown in fig. 3 and 4, the fixing member 3 is fixed to the bottom side of the inner lid 2, and forms a limit groove 30 with the inner lid 2. When assembling, at least one part of the sealing ring 1 can be inserted into the limit groove 30 in a pluggable way and is in limit fit with the limit groove 30. Due to the limitation of the limiting groove 30, the sealing ring 1 can be reliably fixed, and the sealing ring 1 is prevented from falling off; meanwhile, the sealing ring 1 can be conveniently disassembled and assembled due to plugging and unplugging, and is convenient to clean.

The fixing piece 3 can be formed by punching and bending a metal material, for example, the fixing piece is made of stainless steel, the strength is reliable, the deformation is not easy, and the sealing ring 1 can be effectively limited. The fixing part 3 can be fixed to the bottom side of the inner cover 2 by adopting a common welding mode, and the installation is stable and reliable.

In order to reliably support and limit the sealing ring 1, at least three fixing pieces 3 are arranged on the pot cover and are uniformly distributed along the circumferential direction. In the present embodiment, four fixing members 3 are provided on the lid so as to be uniformly distributed in the circumferential direction.

Referring to fig. 3 to 5, the inner cap 2 is of a conventional structure, and has a circular shape, and includes a top wall 21, a side peripheral wall 22 located on a lower side of the top wall 21, and a transition wall 23, the transition wall 23 connecting the top wall 21 and the side peripheral wall 22. The bottom of the side wall 22 is provided with a cover tooth for interlocking with a cover tooth on a cooker body (not shown) to form a cover closing state of the electric pressure cooker. The fixing member 3 includes a connecting portion 31 and a limiting portion 32, the connecting portion 31 is welded to the bottom surface of the top wall 21 for fixing the fixing member 3, and the limiting groove 30 is formed between the limiting portion 32 and the transition wall 23. That is, the fixing member 3 is located inside the seal ring 1, and when the seal ring 1 is assembled, the seal ring 1 is expanded and then contracted, and at least a part of the seal ring 1 enters the limit groove 30, so that the seal ring 1 is not easily dropped. When the sealing ring is disassembled, the sealing ring 1 is expanded, and the part entering the limiting groove 30 is moved out.

The construction of the seal ring 1 is conventional and includes a base 11, an upper lip 12 extending upwardly from the inside of the base 11 and a lower lip 13 extending downwardly from the inside of the base 11. The transition wall 23 is generally L-shaped and includes a vertical section 231, a transverse section 232, and an arcuate section 233 connecting the vertical section 231 and the transverse section 232. The outline of the outer side surfaces of the base part 11 and the upper lip 12 is basically consistent with the shape of the transition wall 23, when the pot cover is covered on the pot body (not shown), the base part 11 and the upper lip 12 are attached to the inner side surface of the transition wall 23 to form sealing connection with the inner cover 2, and the lower lip 13 is connected with the inner pot (not shown) of the pot body in a sealing way. The upper lip 12 includes a root portion 121 connected to the base 11 and a lip portion 122 remote from the base 11. During assembly, firstly, the sealing ring 1 is expanded, the sealing ring 1 is contracted from outside to inside by hand, the whole body moves inwards, namely, the sealing ring moves towards the center, the lip portion 122 penetrates through the limiting groove 30, the root portion 121 is located in the limiting groove 30, the thickness of the root portion 121 can be equal to or smaller than the width of the limiting groove 30, assembly is facilitated, and the thickness of the lip portion 122 can be larger than that of the root portion 121. After assembly, the lip 122 and the limiting groove 30 form a limiting fit, so that the seal ring 1 can be prevented from falling off.

The extension shape of the limiting portion 32 of the fixing member 3 is similar to that of the transition wall 23, and is substantially L-shaped, and includes a first section 321 bent downward from the outer end of the connecting portion 31 and a second section 322 bent outward from the bottom of the first section 321, the first section 321 extends vertically, the second section 322 extends horizontally, and a limiting groove 30 is formed between the end 323 of the second section 322 and the transition wall 23 located at the upper side thereof in the up-down direction. Wherein the first section 321 has a certain curvature, and the first sections 321 of the four fixing members 3 are located on a concentric circle, the center of which coincides with the center of the inner cap 2. The fixing piece 3 is simple in structure and convenient to manufacture.

The end 323 of the second section 322 is provided with a folding edge 324 which is bent upwards and reversely and is overlapped on the upper side of the end 323, burrs left by punching of metal materials can be hidden, and the edge of the end 323 of the second section 322 is an arc smooth surface, so that the sealing ring 1 and fingers of an assembler cannot be scratched during assembly.

A positioning groove 14 is further formed between the upper lip 12 and the lower lip 13, the shape and the size of the positioning groove 14 are basically consistent with those of the tail end 323, and the tail end 323 is positioned in the positioning groove 14, which is equivalent to the sealing ring 1 sleeved on the tail end 323, so that the sealing ring 1 can be further positioned, and the sealing ring 1 is prevented from moving in the radial direction.

The pot cover of the cooking utensil is fixed reliably and conveniently disassembled through the sealing ring 1 fixed by the fixing piece 3, and is easy to clean.
