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 aspects of the present application.

Referring to fig. 1, the present application relates to a pot cover of a cooking appliance, in particular to a pot cover of an electric pressure cooker. The pot cover comprises an inner cover 1 and an upper cover 2 covering the inner cover 1, wherein the inner cover 1 is made of stainless steel and is provided with pot teeth buckled with the pot body. The cooker cover is also provided with a lever 3, an exhaust pipe 4, a pressure limiting valve 5 and an exhaust button 6, the pressure limiting valve 5 is positioned in a containing groove (not numbered) of the upper cover 2, the exhaust pipe 4 penetrates through the inner cover 1 and extends into the containing groove (not numbered), and the exhaust port 41 of the exhaust pipe 4 is blocked by the pressure limiting valve 5. The exhaust button 6 is arranged in the middle of a handle (not numbered) on the top side of the upper cover 2, the lever 3 is a metal rod and is arranged between the inner cover 1 and the upper cover 2, the lever 3 comprises a pivoting part 31 and two support arms 32 respectively arranged at two ends of the pivoting part 31, wherein the tail end of one support arm 32 is arranged below the exhaust button 6, and the tail end of the other support arm 32 is arranged below the pressure limiting valve 5. When a user presses the exhaust button 6, the exhaust button 6 presses down one support arm 32 of the lever 3, then the pivot part 31 is driven to rotate, and the other support arm 32 jacks up the pressure limiting valve 5, so that the exhaust pipe 4 exhausts air outwards, and manual exhaust is realized.

The main improvement of the present application resides in the lever 3 and the fitting structure between the lever 3 and the upper cover 2. As shown in fig. 2 to 5, the upper cover 2 includes a main body 21 and a decorative cover 22 fitted to the main body 21. The exhaust button 6 and the pressure limiting valve 5 are both arranged on the decorative cover 22, and the upper cover 2 adopting a split design can reduce the manufacturing difficulty. The bottom surface of the decoration cover 22 is provided with a projection 221, the top surface 221A of the projection 221 is an upward convex arc surface, and a limit groove 222 is formed between the top surface 221A of the projection 221 and the bottom surface of the decoration cover 22. The pivoting portion 31 of the lever 3 is assembled in the limiting groove 222 and rotates around the protrusion 221. The lug 221 of lid 2 more than 3 of the lever of this application cooking utensil's pot cover rotates as the axle, need not additionally to set up the pin joint axle and be used for the limit structure of location pin joint axle, and the structure is simpler, convenient equipment and manufacturing.

The bottom surface of the decoration cover 22 of the upper cover 2 is provided with two oppositely arranged connecting seats 223, one side of each of the two connecting seats 223 facing each other is provided with a lug 221, and the lug 221 is arranged at the bottom side of the decoration cover 22 through the connection of the connecting seat 223 and forms the limiting groove 222 with the decoration cover 22. Wherein, the connecting seat 223, the protruding block 221 and the decoration cover 22 are formed by integral injection molding, and the manufacture is convenient. The arc of the top surface 221A of the protrusion 221 is close to 180 degrees, preferably greater than 150 degrees, for good contact and support of the pivoting portion 31. The bottom edge 221B of the bump 221 is connected to the connecting seat 223, and the other edges are suspended, so that the bump 221 has a certain elasticity. The pivot portion 31 pushes the protrusion 221 upward and moves over the protrusion 221, and the protrusion 221 is resiliently clamped under the pivot portion 31, so that the pivot portion 31 can be assembled in the retaining groove 222. The width of the gap 224 between the two protrusions 221 is smaller than the width of the pivot portion 31, so as to prevent the pivot portion 31 from falling off. The bottom of the protrusion 221 is provided with a guiding surface 221C for guiding the pivot portion 31 to be assembled upward.

In order to make the pivoting portion 31 rotate smoothly, the upper and lower sides of the limiting groove 222 need to provide a limiting function for the pivoting portion 31, i.e. the bottom surface of the upper cover 2 and the top surface 221A of the protrusion 221 need to cooperate with the pivoting portion 31. The pivoting portion 31 of the lever 3 in this embodiment includes two inner arc sections 311 connected to the two support arms 32, and a middle section 312 connecting the two inner arc sections 311. The lower surfaces of the inner arc sections 311 are concave arc surfaces, the two inner arc sections 311 are located on the same circle, the circle where the circle and the top surface 221A of the protrusion 221 are located is a concentric circle, and the radius of the circle where the inner arc sections 311 are located may be slightly larger than the radius of the circle where the top surface 221A of the protrusion 221 is located. When the lever 3 rotates, the lower surface of the inner arc section 311 is rotationally matched with the top surface 221A of the projection 221, and the middle section 312 abuts against the bottom surface of the top cover 2 upwards, so that the lever 3 is prevented from shaking.

Referring to fig. 6 and 7, the middle section 312 is in an inverted U shape, the top of the middle section 312 is an outer arc section 313, and the upper surface of the outer arc section 313 is an outward convex curved surface, which may be a curved surface formed by smoothly connecting multiple arc surfaces together. When the pivot portion 31 rotates, the outer arc 313 at the top contacts the top surface 221A and rotates relatively, and the outer convex curved surface can make the rotation of the pivot portion 31 smoother and smoother, thereby preventing the upper cover 2 from being scraped.

Fig. 8 to 11 show another embodiment of the lid of the cooking utensil of the present application, which is different from the lid of the previous embodiment mainly in that: the pivot portion 31 ' of the lever 3 ' has a different shape, and the structure of the corresponding decoration cover 22 at the top surface right above the pivot portion 31 ' is also different. Other structures of the cooking appliance, and other portions of the lever and the trim cover are the same as those of the previous embodiment, and a description thereof will not be repeated. Only the differences will be described, wherein the same structure of the decoration cover 22 as that of the previous embodiment will be followed by the previous reference numerals.

The pivot portion 31 'of the lever 3' is generally upwardly convex and substantially corresponds to the arc of the top surface 221A of the protrusion 221. The bottom surface of the decoration cover 22 is provided with a protrusion 221 and a limiting groove 222, and the pivoting portion 31 'of the lever 3' is clamped in the limiting groove 222 and rotates around the protrusion 221. The lever 3' is simpler and easier to form than the lever 3 of the previous embodiment.

The bottom surface of the decoration cover 22 is further provided with a propping block 225 between the two connecting seats 223 for propping the pivoting portion 31, the propping block 225 is provided with a propping surface 226 matched with the top of the pivoting portion 31, and the propping surface 226 is an arc surface to ensure that the pivoting portion 31 can rotate smoothly.

The supporting block 225 further has a groove 227 penetrating through the supporting surface 226, and the groove 227 can reduce the contact area between the supporting surface 226 and the pivoting portion 31, reduce the manufacturing difficulty of the supporting surface 226, and avoid interference to influence the rotation of the pivoting portion 31.
