[0035] Next, the technical solutions of the present utility model will be further described in conjunction with the embodiments and the drawings.

[0036] Embodiment

[0037] Please refer to Figures 1 to 6, an embodiment of the present utility model discloses an electric rice cooker, which includes an electric rice cooker main body and an electric rice cooker lid. The electric rice cooker lid is arranged on the electric rice cooker main body. The electric rice cooker lid of this solution includes a lining 1, a first disassembly and assembly component, a cover plate 3 and a second disassembly and assembly component. The first disassembly and assembly component includes a bracket 21 and a telescopic component 23. One end of the bracket 21 is fixed to the lining 1, and the other end of the bracket 21 is provided with a first movable groove 213 with an opening facing the cover plate 3. The bracket 21 is also provided with a second movable groove 214 penetrating through to the first movable groove 213. The telescopic component 23 is movably arranged in the second movable groove 214 and partially extends into the first movable groove 213. The second disassembly and assembly component is arranged on the cover plate 3. The second disassembly and assembly component extends into the first movable groove 213 and is detachably connected to the telescopic component 23, so that the cover plate 3 is detachably connected to the lining 1. With such a design method, the disassembly and assembly of the cover plate 3 are realized by setting the first disassembly and assembly component including the bracket 21 and the telescopic component 23 and the second disassembly and assembly component. On the one hand, it can ensure that the cover plate 3 is installed in place on the lining 1, thus avoiding air leakage of the cover plate 3 assembly. On the other hand, it can also meet the installation requirements under the condition of simple structure and low cost.

[0038] Further, in order for the second disassembly and assembly component to be detachably connected to the telescopic component 23, the second disassembly and assembly component includes a connecting piece 42 and a boosting block 43. One end of the connecting piece 42 is movably connected to the cover plate 3 and the other end is provided with a limiting portion 421. The boosting block 43 is movably sleeved on the connecting piece 42. Among them, when the other end of the connecting piece 42 extends into the first movable groove 213 and the limiting portion 421 presses the telescopic component 23, the telescopic component 23 retracts into the second movable groove 214, so that the limiting portion 421 can cross over the telescopic component 23. When the pressing action of the limiting portion 421 is cancelled, the telescopic component 23 resets to extend into the first movable groove 213 to limit the limiting portion 421 on the bracket 21. When the boosting block 43 presses the telescopic component 23, the telescopic component 23 retracts into the second movable groove 214, and the limiting portion 421 crosses over the telescopic component 23 under the action of external force to detach the second disassembly and assembly component from the telescopic component 23.

[0039] In some embodiments, in order for the telescopic component 23 to retract into the second movable groove 214 under the pressing of the limiting portion 421, a guiding arc surface 4211 for guiding the telescopic component 23 is provided on the side of the limiting portion 421 facing the bracket 21. With such a design method, since the guiding arc surface 4211 is provided on the limiting portion 421, the limiting portion 421 presses the telescopic component 23 through the guiding arc surface 4211, so that while the limiting portion 421 presses the telescopic component 23, the telescopic component 23 can expand and contract along the second movable groove 214.

[0040] Similarly, in order for the telescopic member 23 to retract into the second movable groove 214 under the extrusion of the boosting block 43, a first guiding inclined surface 431 for guiding the telescopic member 23 is provided on one side of the boosting block 43 facing the bracket 21.

[0041] Furthermore, in order to prevent the limiting portion 421 from moving towards the bracket 21 when the boosting block 43 extrudes the telescopic member 23, which may affect the disassembly of the limiting portion 421, preferably, a groove 4212 whose shape is adapted to the first guiding inclined surface 431 is provided on the side of the limiting portion 421 facing away from the bracket 21. With such a design, when the boosting block 43 extrudes the telescopic member 23, it extends into the groove 4212. Moreover, when the telescopic member 23 retracts into the second movable groove 214, the boosting block 43 squeezes the telescopic member 23 and forms an integral body with the limiting portion 421. Pulling the cover plate 3 can make the limiting portion 421 cross over the telescopic member 23 following the boosting block 43.

[0042] In some embodiments, in order for the limiting portion 421 to better cross over the telescopic member 23 after extruding the telescopic member 23, the second disassembly and assembly component further includes a first return spring 44, and the first return spring 44 abuts between the cover plate 3 and the connecting member 42. With such a design, when pushing the cover plate 3 towards the inner lining 1, the guiding arc surface 4211 of the limiting portion 421 and the telescopic member 23, when the guiding arc surface 4211 of the limiting portion 421 is higher than the telescopic member 23, under the action of the first return spring 44, the limiting portion 421 continues to displace in the direction towards the limiting portion 421. At this time, releasing the cover plate 3, both the cover plate 3 and the boosting block 43 move downward under gravity, and the limiting portion 421 is stuck on the telescopic member 23.

[0043] Furthermore, in order to realize the installation of the connecting member 42 and the first return spring 44 on the cover plate 3, a third movable groove 41 with an opening is provided on the side of the cover plate 3 facing the inner lining 1. One end of the connecting member 42 is provided with a limiting block 423, the other end of the connecting member 42 movably passes through the opening and extends into the third movable groove 41, the limiting block 423 is located in the third movable groove 41, and the first return spring 44 abuts between the limiting block 423 and the inner wall surface of the third movable groove 41.

[0044] Furthermore, in order to realize the limitation between the first return spring 44 and the connecting member 42, a limiting groove 422 is provided at the other end of the connecting member 42, and the end of the first return spring 44 extends into the limiting groove 422.

[0045] In some embodiments, the retractable component 23 includes a second return spring 231 and an active buckle 232. The second return spring 231 is located in the second active groove 214 and one end thereof abuts against the inner wall surface of the second active groove 214. One end of the active buckle 232 abuts against the other end of the second return spring 231 and the other end of the active buckle 232 extends into the first active groove 213. With such a design, when the other end of the connecting member 42 extends into the first active groove 213, the active buckle 232 retracts into the second active groove 214 under the pressure of the limiting portion 421. When the pressure of the limiting portion 421 on the active buckle 232 is cancelled, the active buckle 232 is reset to extend into the first active groove 213 under the action of the second return spring 231.

[0046] Specifically, there are two second movable grooves 214, two movable buckles 232 and two second return springs 231, and the two second movable grooves 214 are arranged opposite to each other. The two movable buckles 232 and the two second return springs 231 are respectively arranged on the two second movable grooves 214. With such a design, the two movable buckles 232 have a good limiting effect. It is understandable that in other embodiments, the design of only one or more than three second movable grooves 214, movable buckles 232 and second return springs 231 can also be adopted, which is not limited here.

[0047] Furthermore, in order to limit the cover plate 3 after the movable buckle 232 is reset, a limiting surface 2321 for limiting the limiting portion 421 on the bracket 21 is provided on the side of the movable buckle 232 facing the lining 1, and in order to enable the movable buckle 232 to retract to the second movable groove 214 when the limiting portion 421 is pressed toward the bracket 21, a second guide slope 2322 for guiding the limiting portion 421 is provided on the side of the movable buckle 232 facing the cover plate 3.

[0048] Furthermore, in order to prevent the movable buckle 232 from slipping at the abutment with the second return spring 231 when the movable buckle 232 compresses the second return spring 231 or the second return spring 231 pushes the movable buckle 232 to return, a positioning column 2323 is provided on the movable buckle 232, and the end of the second return spring 231 is sleeved outside the positioning column 2323.

[0049] In some embodiments, a first limiting boss 2141 is provided in the second movable groove 214 , and a second limiting boss 2324 is provided on the movable buckle 232 . The first limiting boss 2141 limits the second limiting boss 2324 to prevent the movable buckle 232 from escaping from the second movable groove 214 .

[0050] Further, considering that the second limiting boss 2324 is provided on the movable buckle 232, for the convenience of installing the movable buckle 232, the bracket 21 includes an upper bracket 211 and a lower bracket 212. One end of the upper bracket 211 is fixed to the inner lining 1, and the lower bracket 212 is fixed to the upper bracket 211 and forms a second movable groove 214 in alignment with the upper bracket 211. During installation, the second return spring 231 and the movable buckle 232 can be first placed on the upper bracket 211 or the lower bracket 212, and then the lower bracket 212 and the upper bracket 211 are aligned and fixed.

[0051] In some embodiments, in order to facilitate the installation and disassembly of the cover plate 3, a holding portion 31 is provided on the side of the cover plate 3 facing away from the inner lining 1. With such a design, the user can apply a pushing force for installation and a pulling force for disassembly to the cover plate 3 by holding the holding portion 31.

[0052] The following describes in detail the process of installing the cover plate 3 on the inner lining 1:

[0053] As Figure 1 → Figure 2 → Figure 3 As shown, first fix the bracket 21 on the inner lining 1 to install the first disassembly and assembly component on the inner lining 1, then align the connecting member 42 with the first movable groove 213, and push the cover plate 3 in the direction towards the inner lining 1. The guiding arc surface 4211 of the limiting portion 421 of the connecting member 42 presses the second guiding inclined surface 2322 of the movable buckle 232. At this time, the movable buckle 232 compresses the second return spring 231 under the action of the limiting portion 421 and retracts into the second movable groove 214. At the same time, the connecting member 42 presses the first return spring 44 under the action of the movable buckle 232. When the guiding arc surface 4211 of the limiting portion 421 is higher than the limiting surface 2321 of the movable buckle 232, the connecting member 42 moves upward under the action of the first return spring 44 so that the limiting portion 421 crosses over the movable buckle 232. Then, the pressure applied to the cover plate 3 is removed. When the pressing action of the limiting portion 421 is removed, the second return spring 231 resets and drives the movable buckle 232 to reset and penetrate out of the second movable groove 214. The cover plate 3 and the boosting block 43 move downward under the action of gravity, and the limiting portion 421 is stuck on the movable buckle 232 to limit the cover plate 3 on the bracket 21, thereby realizing the installation and positioning of the cover plate 3 on the inner lining 1.

[0054] The following describes in detail the process of disassembling the cover plate 3 from the inner lining 1:

[0055] As Figure 3 → Figure 2 → Figure 1As shown in the figure, when the cover plate 3 is pushed in the direction towards the inner liner 1, under the push of the cover plate 3, the first guiding inclined surface 431 of the boosting block 43 presses against the second guiding inclined surface 2322 of the movable buckle 232. At this time, under the action of the boosting block 43, the movable buckle 232 compresses the second reset spring 231 and retracts into the second movable slot 214. Then, when the cover plate 3 is pulled in the direction away from the inner liner 1, the limiting portion 421 crosses over the movable buckle 232 under the action of an external force, so as to detach the second disassembly and assembly component from the telescopic component 23, thereby realizing the disassembly of the cover plate 3.

[0056] An electric rice cooker provided by the present utility model includes an electric rice cooker cover provided with an inner liner 1, a first disassembly and assembly component, a cover plate 3 and a second disassembly and assembly component. The first disassembly and assembly component includes a bracket 21 and a telescopic component 23. One end of the bracket 21 is fixed to the inner liner 1, and the other end of the bracket 21 is provided with a first movable slot 213 with an opening facing the cover plate 3. The bracket 21 is further provided with a second movable slot 214 penetrating through to the first movable slot 213. The telescopic component 23 is movably arranged in the second movable slot 214 and partially extends into the first movable slot 213. The second disassembly and assembly component is arranged on the cover plate 3, and the second disassembly and assembly component extends into the first movable slot 213 and is detachably connected to the telescopic component 23, so that the cover plate 3 is detachably connected to the inner liner 1. By adopting such a design method, the disassembly and assembly of the cover plate 3 are realized by setting the first disassembly and assembly component including the bracket 21 and the telescopic component 23 and the second disassembly and assembly component. On the one hand, it can ensure that the cover plate 3 is installed in place on the inner liner 1, thereby avoiding air leakage of the cover plate assembly. On the other hand, it can also meet the installation requirements with a simple structure and low cost.
