[0036] Figure 1 The utility model shows a three-dimensional structural schematic diagram of the electric rice cooker cover opening button structure when it is installed on the electric rice cooker. Figure 2 The utility model shows a cross-sectional structural diagram of the electric rice cooker cover opening button structure when it is installed on the electric rice cooker. Figure 3 A partial enlarged view of the rice cooker cover opening button structure at position A of the present invention is shown. Figure 4The three-dimensional structure diagram of the rice cooker cover opening button structure of the utility model is shown. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The rice cooker lid opening button structure is arranged on the cooker body 1 and cooperates with the hook 21 on the cooker lid 2. The rice cooker lid opening button structure includes a lid opening button 3, a button bracket 4 and a body buckle 6. The lid opening button 3 includes a connecting section 31 and a pressing section 32. The connecting section 31 is rotatably connected to the button bracket 4. The body buckle 6 includes a supporting section 61, a first swinging section 62 and a second swinging section 63. The supporting section 61 is rotatably connected to the button bracket 4. The first swinging section 62 is arranged between the pressing section 32 and the button bracket 4. A hook 631 is provided on the second swinging section 63. Among them, the hook 21 is arranged on the side of the second swinging section 63 away from the lid button 3. When locked, the upper part of the hook 21 contacts the lower part of the hook 631. When the lid opening button 3 is pressed, the pressing section 32 squeezes the first swinging section 62 and drives the second swinging section 63 away from the hook 21. By pressing the main body latch 6, the pressing section 32 squeezes the first swinging section 62, driving the hook 631 out of the hook 21, thereby unlocking the rice cooker body 1 and the lid 2. The lid-opening button 3 and the main body latch 6 are both mounted on the button bracket 4, allowing the lid-opening button 3 and the main body latch 6 to be pre-secured on the button bracket 4. In this way, the lid-opening button 3, button bracket 4, and main body latch 6 are first assembled as a single unit outside the rice cooker body 1, and then the entire unit is installed on the rice cooker body 1. This reduces the connection, alignment, and securing requirements between the various components and the rice cooker body 1, thereby simplifying the assembly process of the rice cooker lid-opening button structure and reducing assembly time and complexity.

[0037] Figure 5 The utility model shows a three-dimensional structural diagram of the lower bracket of the electric rice cooker cover opening button structure. Figure 6 The utility model shows a schematic diagram of the three-dimensional structure of the upper bracket of the electric rice cooker cover opening button structure. Figure 7 The figure shows the three-dimensional structure of the cover opening button in the rice cooker cover opening button structure of the present invention. Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The key support 4 includes an upper support 42 and a lower support 41. A positioning post 421 is provided on the upper support 42, and a connecting hole 413 is provided on the lower support 41 for the positioning post 421 to extend into. The positioning post 421 extends into the connecting hole 413 to quickly determine the positional relationship between the upper support 42 and the lower support 41. Fasteners are then simultaneously inserted through the connecting hole 413 and the positioning post 421 to secure the upper support 42 and the lower support 41. Assembly of the upper support 42 and the lower support 41 is simple. By inserting the fasteners through the connecting hole 413 and the positioning post 421 and then connecting to the pot body 1, the key support 4 can be conveniently secured to the pot body 1.

[0038] Preferably, a limit window 411 is defined in the lower bracket 41, into which the pressing section 32 extends. The limit window 411 limits the travel of the pressing section 32. Furthermore, the first swinging section 62 is disposed between the pressing section 32 and the lower bracket 41. When the travel of the pressing section 32 is limited, the travel of the first swinging section 62 is also limited.

[0039] Preferably, first rotating posts 311 are symmetrically disposed on either side of the connecting section 31. Extending from the button bracket 4 are lever arms 414, each of which defines a circular groove 415 for the first rotating posts 311 to extend into. When assembling the connecting section 31 and the button bracket 4, an operator applying force to the lever arms 414 generates a significant torque, making them more easily bent. This facilitates assembly between the first rotating posts 311 and the circular groove 415.

[0040] Please refer to Figure 3 and Figure 7 An elastic member 5 is provided between the pressing section 32 and the key bracket 4, and the elastic member 5 and the first swing section 62 are provided on the same side of the pressing section 32. After the operator squeezes the pressing section 32, the pressing section 32 rebounds through the elastic member 5.

[0041] Preferably, a first positioning protrusion 321 is extended from the pressing section 32. A second positioning protrusion 412 is extended from the key bracket 4. One end of the elastic member 5 is connected to the first positioning protrusion 321, and the other end of the elastic member 5 is connected to the second positioning protrusion 412. The two ends of the elastic member 5 are positioned and fixed by the first positioning protrusion 321 and the second positioning protrusion 412, which facilitates the installation and fixing of the elastic member 5.

[0042] More preferably, the elastic member 5 is a spring, and the first positioning protrusion 321 and the second positioning protrusion 412 are cross-shaped protrusions. The cross-shaped protrusion is formed by two straight sides perpendicular to each other and splitting the center. The cross-shaped protrusion design allows the spring to automatically align when connected to the cross-shaped protrusion, reducing installation difficulty and improving assembly efficiency. The cross-shaped protrusion design also provides better support and stability, allowing the spring to maintain accurate positioning even when subjected to external forces or vibrations.

[0043] Figure 8 The figure shows the three-dimensional structure of the main body buckle in the rice cooker cover opening button structure of the utility model. Figure 3 and Figure 8 The main body buckle 6 is provided with a buckle torsion spring 7. The torsion arm 71 of the buckle torsion spring 7 abuts the side of the first swinging section 62 away from the cover button 3, while the connecting arm 72 of the buckle torsion spring 7 abuts the button bracket 4. When the operator squeezes the pressing section 32, driving the buckle torsion spring 7 to rotate, the buckle torsion spring 7 can then drive the main body buckle 6 to rotate and reset.

[0044] The first swing section 62 is provided with a torsion spring slot 621, and a support column 622 is provided in the torsion spring slot 621. The buckle torsion spring 7 is connected to the first swing section 62 via the support column 622. The support column 622 is provided inside the first swing section 62, making the structure of the main buckle 6 more compact.

[0045] Second rotating posts 611 are symmetrically positioned on either side of the body clip 6. The button bracket 4 is provided with a support plate 422, which defines a rotation hole 423 for the second rotating posts 611 to extend into. When assembling the body clip 6 and the button bracket 4, the operator applies force to the support plate 422, generating a significant torque. This allows the structure to bend more easily, facilitating assembly between the body clip 6 and the button bracket 4.

[0046] The specific workflow of this utility model is as follows:

[0047] To unlock the pot body 1 and lid 2, the operator presses the pressing section 32, causing it to rotate about the button bracket 4. The rotating pressing section 32 pushes the first swinging section 62, causing the body buckle 6 to rotate about the second rotating post 611. The second swinging section 63 moves away from the hook 21, and the hook 631 disengages from the hook 21. The pot body 1 and lid 2 are now unlocked and can be separated.

[0048] To lock the pot body 1 and lid 2, the operator presses the pressing section 32, causing it to rotate about the button bracket 4. The rotating pressing section 32 pushes the first swinging section 62, causing the main body clip 6 to rotate about the second rotating column 611, and the second swinging section 63 to move away from the hook 21. The pot body 1 and lid 2 are then closed, and the operator releases the pressing section 32. The elastic member 5 pushes the pressing section 32 away from the first swinging section 62. The torsion spring drives the main body clip 6 to rotate in the opposite direction about the support section 61, causing the second swinging section 63 to approach the hook 21, and the hook portion 631 contacts the hook 21. The pot body 1 and lid 2 are then locked.

[0049] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
