[0006] In the above cooking utensil, the rib is the arc-shaped rib half-wrapped on the outside of through hole, two limiting ribs are symmetrically arranged on the left and right sides of pressing part, and the limiting rib extends radially outward from the outer circumferential side of the pressing part.

[0007] In the above cooking utensil, the arc-shaped rib is half-wrapped on the lower side of the through hole.

[0008] In the above cooking utensil, the number of ribs is two, and the two ribs are respectively located on the left and right sides of the through hole, and the limiting rib is wrapped around the outer circumferential side of the pressing part.

[0009] In the cooking utensil, a gap is present between the outer circumferential side of the pressing part and the hole wall of the through hole, the outer circumferential side of the pressing part is provided with a shielding rib, and a projection of the shielding rib to the direction of the through hole covers the gap.

[0010] In the cooking utensil, the convex rib is located outside the projection of the shielding rib to the direction of the through hole.

[0011] In the cooking utensil, the shielding rib and the limiting rib are cross-connected, and at least part of the limiting rib is convex on one side of the shielding rib facing the through hole.

[0012] In the cooking utensil, the cover opening button rotates around the first axis, the hole wall of the through hole away from the first axis is provided with a curved surface, the pressing part has a first end farthest from the first axis, and the curved surface corresponds to a track surface formed by rotation of the first end around the first axis.

[0013] In the cooking utensil, the first axis is higher than the through hole, and the curved surface is located below the pressing part.

[0014] In the cooking utensil, the cover opening button further comprises a hinged part connected between the pressing part and the clamping part, the hinged part is pivoted to the shell, the shell is provided with a first mounting plate, a spring is arranged between the first mounting plate and the pressing part, the spring drives the cover opening button to rotate and reset, so that the limiting rib cooperates with the convex rib.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1、In the embodiment, the part of the shell inside located around the through hole is provided with a convex rib, the pressing part is provided with a limiting rib, the limiting rib cooperates with the convex rib to limit the protruding height of the left and right sides of the pressing part relative to the outer surface of the shell, such design not only saves the decorative ring to reduce the number of parts of the pot body and the assembly difficulty, but also can limit the protruding height of the left and right sides of the pressing part relative to the outer surface of the shell through the cooperation of the limiting rib and the convex rib, and make the protruding height of the left and right sides of the pressing part relative to the outer surface of the shell consistent, so as to ensure the overall appearance of the pot body and make the pot body more beautiful.

[0017] 2. The protruding rib is an arc-shaped rib that partially encloses the outside of the through hole. Two limiting ribs are symmetrically arranged on the left and right sides of the pressing part, and the limiting ribs extend radially outward from the outer periphery of the pressing part. Compared to setting a raised rib on each side of the through hole to correspond to two limiting ribs respectively, this technical solution, by designing the raised rib as an arc-shaped rib, avoids the problem of the two limiting ribs not being able to match the raised rib due to processing and assembly errors. This reduces the processing difficulty of the shell and the assembly of the shell and the opening button, while also enhancing the structural strength of the raised rib. In addition, compared to the ring rib, the arc-shaped rib design also reduces the surface defect area on the outer surface of the shell caused by the presence of the raised rib, thereby improving the appearance of the shell. Secondly, by setting the two limiting ribs separately, the material cost of the opening button can also be reduced. Furthermore, the limiting rib extends radially outward from the outer periphery of the pressing part, which can increase the vertical and radial matching range of the limiting rib. Even if the pressing part is slightly offset in the left-right or up-down direction, it can still ensure that the limiting rib matches the raised rib. Finally, when one side of the opening button protrudes more in the left-right direction, the limiting rib on that side can be thinned by grinding or other methods to reduce the protrusion height on that side, so as to ensure that the protrusion degree on the left and right sides of the opening button is consistent.

[0018] 3. The raised rib is an arc-shaped rib that partially encloses the lower side of the through hole. By having the arc-shaped rib partially enclose the lower side of the through hole, surface defects that appear on the outer surface of the shell at the location corresponding to the arc-shaped rib are placed in a less observable position, thus avoiding easy observation by the user.

[0019] 4. There are two raised ribs, located on the left and right sides of the through hole, respectively, with the limiting ribs surrounding the outer periphery of the pressing part. This design further reduces the surface defect area caused by the raised ribs on the outer surface of the shell, thereby improving the appearance of the shell. It also avoids the problem of the two raised ribs not corresponding to the limiting ribs due to processing and assembly errors. Finally, if one side of the opening button protrudes significantly, the raised rib on that side can be thinned by grinding or other methods to reduce the protrusion height on that side, ensuring that the protrusion height of the opening button on both sides relative to the outer surface of the shell is consistent.

[0020] 5. There is a gap between the outer periphery of the pressing part and the wall of the through hole. A shielding rib is provided on the outer periphery of the pressing part, and the projection of the shielding rib toward the through hole covers the gap. This design can block the gap between the lid opening button and the through hole by the shielding rib, so as to prevent the user from seeing the environment inside the outer shell from the outside of the pot.

[0021] 6. The raised rib is located on the outer side of the projection of the shielding rib towards the through hole. This design prevents the user from seeing the raised rib from the outside of the pot body, thus improving the user experience.

[0022] 7. The blocking rib and the limiting rib are cross-connected, and at least part of the limiting rib is protruded on one side of the blocking rib facing the through hole. In this way, the structural strength of the limiting rib is enhanced, the fracture of the limiting rib during adjustment is avoided, and the structure of the uncovering button is more compact.

[0023] 8. The uncovering button rotates around the first axis, the hole wall on the side of the through hole away from the first axis is provided with a curved surface, the pressing part has a first end farthest from the first axis, and the curved surface corresponds to the trajectory surface formed by the rotation of the first end around the first axis. In the prior art, the hole wall of the through hole is provided as a cylindrical surface, and in the initial stage of the rotation of the first end around the first axis due to the pressing of the pressing part, the gap between the hole wall of the through hole and the first end gradually decreases, so that the uncovering button is stuck and cannot be reset. According to the technical scheme, the curved surface corresponds to the trajectory surface formed by the rotation of the first end around the first axis, so that in the initial stage of the rotation of the pressing part due to the pressing, the gap between the curved surface and the pressing part is kept unchanged, thereby eliminating the risk of sticking and being unable to reset.

[0024] 9. The first axis is higher than the through hole, and the curved surface is located below the pressing part. In this way, the structure is simple and easy to set.

[0025] 10. The uncovering button further comprises a hinged part connected between the pressing part and the clamping part, the hinged part is pivoted to the shell, the shell is provided with a first mounting plate, a spring is arranged between the first mounting plate and the pressing part, and the spring drives the uncovering button to rotate and reset, so that the limiting rib cooperates with the protruding rib. In this way, after the pressing of the pressing part is cancelled, the restoring force of the spring can drive the uncovering button to rotate and reset, so that the pressing part returns to the initial position, and the clamping part can be clamped with the cover body after the cover body is closed again.

[0038] Example 1

[0039] like Figures 1 to 5 As shown, the cooking appliance in this embodiment includes a pot body 100 and a lid 200. The pot body 100 includes an outer shell 110 and an outer pot 120. The outer shell 110 is provided with a through hole 111. An opening button 130 is pivotally connected to the outer shell 110 and the outer pot 120. The opening button 130 has a locking part 131 that engages with the lid 200 and a pressing part 132 that penetrates the through hole 111. The inner side of the outer shell 110 is provided with a rib 112 around the through hole 111. The outer periphery of the pressing part 132 is provided with a limiting rib 133. The limiting rib 133 cooperates with the rib 112 so that the left and right sides of the pressing part 132 protrude from the outer surface of the outer shell 110 at the same height. This design not only eliminates the need for decorative rings, reducing the number of parts and assembly difficulty of the pot body, but also limits the protrusion height of the left and right sides of the pressing part 132 relative to the outer surface of the outer shell 110 by cooperating with the limiting rib 133 and the protruding rib 112. By making the protrusion height of the left and right sides of the pressing part 132 relative to the outer surface of the outer shell 110 consistent, the overall appearance of the pot body 100 is guaranteed, making the pot body 100 more beautiful.

[0040] Specifically, in this embodiment, the cover-opening button 130 further includes a hinge portion 134, which connects the pressing portion 132 and the locking portion 131. The outer casing 110 includes a body 113 and a central ring 114 mounted on the top of the body 113. The central ring 114 has two second mounting plates 1141 extending downward and spaced apart on the left and right sides. Each of the two second mounting plates 1141 has a mounting hole. The left and right sides of the hinge portion 134 have rotating shafts 1341, which rotate and engage with the mounting holes to achieve pivotal connection between the hinge portion 134 and the outer casing 110. A through hole 111 is provided on the body 113, and The pivot 1341 is positioned above the through hole 111, and the snap-fit ​​part 131 is connected to the top of the hinge part 134 and extends upward through the top wall of the middle ring 114 before protruding outside the outer shell 110. The pressing part 132 is connected to the bottom of the hinge part 134 and extends downward. A gap 001 is provided between the pressing part 132 and the hole wall of the through hole 111. In order to ensure the uniformity of the gap 001, it is necessary to ensure that the body 113 and the middle ring 114 are relatively fixed in the circumferential direction. Therefore, in this embodiment, the top of the body 113 is provided with a positioning notch 1130, and the middle ring 114 is provided with a positioning part 1140 that is inserted into the positioning notch 1130.

[0041] The through hole 111 in the embodiment is a circular hole, the pressing portion 132 is a cylindrical structure, the convex rib 112 is an arc-shaped rib half-wrapped outside the through hole 111, and the two limiting ribs 133 are symmetrically arranged on the left and right sides of the pressing portion 132 and extend radially outward from the outer circumferential side of the pressing portion 132. In this way, compared with arranging one convex rib 112 on each of the left and right sides of the through hole 111 so that it corresponds to two limiting ribs 133 respectively, the technical solution can avoid the problem that the two limiting ribs 133 cannot correspond to the convex rib 112 due to processing and assembly errors, thereby reducing the processing difficulty of the shell 110 and the assembly difficulty of the shell 110 and the cover-opening button 130, and also enhancing the structural strength of the convex rib 112. In addition, compared with an annular rib, the design of the arc-shaped rib also reduces the surface defect area of the outer surface of the shell 110 due to the existence of the convex rib 112, so as to improve the appearance of the shell 110. Secondly, by arranging the two limiting ribs 133 apart, the material cost of the cover-opening button 130 can also be reduced. Furthermore, the limiting rib 133 extends radially outward from the outer circumferential side of the pressing portion 132, which can increase the vertical and radial matching range of the limiting rib 133, so that the limiting rib 133 can match the convex rib 112 even if the pressing portion 132 slightly deviates in the left-right direction or the up-down direction. Finally, when one side of the cover-opening button 130 protrudes more in the left-right direction, the limiting rib 133 on that side can be thinned by grinding or other methods to reduce the protrusion height of that side, so as to ensure that the protrusion degrees of the left and right sides of the cover-opening button 130 are consistent.

[0042] The length L of the radial extension of the limiting rib 133 in the embodiment is greater than the size L1 of the limiting rib 133 in the circumferential direction of the pressing portion 132, so that the radial cross section of the limiting rib 133 is rectangular, and the limiting rib 133 and the convex rib 112 match in a cross shape. By reducing the radial cross-sectional area of the limiting rib 133, the contact area of the limiting rib 133 and the convex rib 112 can be reduced, thereby reducing the processing precision requirement of the side of the limiting rib 133 facing the convex rib 112, and when the thickness (the axial dimension along the pressing portion 132) of the limiting rib 133 needs to be adjusted, only a small area needs to be polished, and the adjustment is simple and convenient.

[0043] The convex rib 112 in the embodiment is an arc-shaped rib half-wrapped under the through hole 111. By half-wrapping the arc-shaped rib under the through hole 111, the surface defect on the outer surface of the shell 110 corresponding to the arc-shaped rib can be made to be in a position that is not easy to observe, so as to avoid being easily observed by the user.

[0044] After assembly, the gap 001 exists between the outer periphery of the pressing portion 132 and the hole wall of the through hole 111, and the outer periphery of the pressing portion 132 is provided with a shielding rib 135 extending radially outward, the shielding rib 135 is an annular rib, and the projection of the shielding rib 135 in the direction of the through hole 111 covers the gap 001. In this way, the gap 001 between the pressing portion 132 and the through hole 111 can be shielded by the shielding rib 135 to prevent the user from seeing the environment inside the shell 110 from the outside of the pot body 100.

[0045] Preferably, the convex rib 112 is located outside the projection of the shielding rib 135 in the direction of the through hole 111. In this way, the user can be prevented from seeing the convex rib 112 from the outside of the pot body 100, thereby improving the user's experience.

[0046] In addition, the shielding rib 135 and the limiting rib 133 are cross-connected in the embodiment, and at least part of the limiting rib 133 protrudes from one side of the shielding rib 135 toward the through hole 111. In this way, the structural strength of the limiting rib 133 can be enhanced by connecting the limiting rib 133 and the shielding rib 135, thereby preventing the limiting rib 133 from breaking during adjustment, and also making the structure of the cover opening button 130 more compact.

[0047] The cover opening button 130 in the embodiment rotates around a first axis, which is the axis of the rotating shaft 1341. The bottom of the pressing portion 132 has a first end 1321 farthest from the first axis. In the prior art, the hole wall of the through hole 111 is provided as a cylindrical surface. When the pressing portion 132 is pressed and the first end 1321 rotates around the first axis in the initial stage, the gap between the hole wall of the through hole and the first end 1321 will gradually decrease, which may cause the cover opening button 130 to be stuck and unable to reset. Figure 4 As shown in the drawings, the hole wall of the through hole 111 far from the first axis is provided with an arc surface 1110, i.e., the arc surface 1110 is located below the pressing portion 132. The arc surface 1110 corresponds to the trajectory surface G formed by the rotation of the first end around the first axis, i.e., the center of the arc surface 1110 is located on the first axis, and the radius of the arc surface 1110 is greater than the distance between the first end 1321 and the first axis. The distance between the arc surface 1110 and the trajectory surface G can be 1mm-3mm. In this way, by making the arc surface 1110 correspond to the trajectory surface G, the gap 001 between the arc surface 1110 and the pressing portion 132 can be kept unchanged in the initial stage of the rotation of the pressing portion 132, thereby eliminating the risk of being stuck and unable to reset.

[0048] Finally, the middle ring 114 in the embodiment is further provided with a first mounting plate 1142 extending downward, the first mounting plate 1142 is located on the side of the pressing part 132 away from the through hole 111, a spring 140 is arranged between the first mounting plate 1142 and the pressing part 132, the spring 140 is a compression spring, the first mounting plate 1142 and the pressing part 132 are respectively provided with positioning protrusions, the two ends of the compression spring are sleeved on the positioning protrusions respectively, so that the spring 140 is clamped between the first mounting plate 1142 and the pressing part 132, the spring 140 has a tendency to rotate the pressing part 132 towards the through hole 111, under normal circumstances (i.e. when the pressing part 132 is not pressed), the spring 140 drives the cover opening button 130 to rotate and reset, so that the limiting ribs 133 cooperate with the convex ribs 112, at this time, after the cover body 200 is covered on the pot body 100, the buckle on the cover body 200 can be clamped and fixed with the clamping part 131, when the user presses the pressing part 132 to drive the cover opening button 130 to rotate, the spring 140 is compressed, and at the same time, the clamping part 131 is separated from the buckle, so that the cover body 200 can be opened, and after the pressing on the pressing part 132 is cancelled, the restoring force of the spring 140 can drive the cover opening button 130 to rotate and reset, so that the pressing part 132 returns to the initial position, so as to facilitate the cover body 200 to be covered again and clamped with the clamping part 131.

[0049] It can be understood that in other embodiments, the convex ribs can also be annular ribs arranged around the through hole or arc-shaped ribs semi-enclosed on the upper side of the through hole.

[0050] Embodiment two

[0051] Compared with the embodiment one, the difference of the embodiment is that the number of the convex ribs is two, the two convex ribs are respectively located on the left and right sides of the through hole, and the limiting ribs are arranged around the outer circumferential side of the pressing part, i.e. the shielding ribs can form the limiting ribs. In this way, the surface defect area of the outer surface of the shell caused by the convex ribs can be further reduced, so as to further improve the appearance of the shell; at the same time, the problem that the two convex ribs cannot be matched with the limiting ribs due to the machining and assembly errors can also be avoided; finally, when one side of the cover opening button protrudes more in the left-right direction, the convex rib on the side can be thinned by grinding or other methods to reduce the protrusion height of the side, so as to ensure that the protrusion heights of the left and right sides of the cover opening button relative to the outer surface of the shell are consistent.

[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, and those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific implementation.
