[0039] First embodiment

[0040] ​The electromagnetic adsorption assembly 2 includes a shell support 21 and an electromagnetic valve 22 placed in the shell support 21. The shell support 21 is fixed to the top center of the inner liner 3. The electromagnetic adsorption assembly 2 is installed at the top center of the inner liner 3, which is more conducive to the stable adsorption of the inner cover 4. The fixation of the shell support 21 ensures that the electromagnetic valve 22 can remain stable during operation and is not easily affected by external interference, ensuring the working precision and response speed of the electromagnetic valve 22. By fixing the shell support 21 to the top center of the inner liner 3, the electromagnetic adsorption assembly 2 is in a stable position in the entire cooking utensil, enabling the adsorption function of the electromagnetic valve 22 to be accurately performed. Installing the electromagnetic adsorption assembly 2 at the top center of the inner liner 3 helps to ensure that the suction force generated by the electromagnetic valve 22 can act uniformly and stably on the inner cover 4, avoiding uneven or unstable adsorption of the inner cover 4. This design ensures that the inner cover 4 can be accurately aligned during adsorption, preventing the inner cover 4 from falling due to insufficient stability when the pot cover is opened. Installing the electromagnetic adsorption assembly 2 at the top center of the inner liner 3 can effectively optimize the spatial layout, enabling the suction force of the electromagnetic valve 22 to be more concentrated on the inner cover 4. The design and installation position of the electromagnetic adsorption assembly 2 help to reduce the delay caused by asymmetric or unstable components. By placing the electromagnetic adsorption assembly 2 at the top center of the inner liner 3, it can ensure that the electromagnetic valve 22 quickly generates suction force and accurately controls the adsorption or release of the inner cover 4, thereby improving the response speed of the system.

The coil component 221 generates a magnetic field through electric current. When electric current passes through the coil, a magnetic field is generated, driving the movement of the magnet member 223. When the coil component 221 is connected to the power supply, the generated magnetic field attracts the magnet member 223. When the coil component 221 is disconnected from the power supply, the magnetic field disappears, and the magnet member 223 returns to its original position (through the action of the elastic member 222). The elastic member 222 provides a restoring force, ensuring that the magnet member 223 automatically returns to the original position when there is no electric current.

[0042] The coil component 221 is provided with a limiting portion 2222, the elastic member 222 is sleeved on the limiting portion 2222, the magnet member 223 passes through the limiting portion 2222, the coil component 221 is used for generating a magnetic field force greater than the elastic force of the elastic member 222 when the power is turned on, the coil component 221 adsorbs the magnet member 223 away from the inner cover 4 so that the inner cover 4 is not adsorbed, and the elastic member 222 is used for pressing the magnet member 223 and making the magnet member 223 press the inner liner 3, and the limiting portion 2222 is used for limiting the movement stroke of the magnet member 223.

The inside of the suction accessory 41 is provided with a magnetic conductor 411, and the magnet member 223 is used for adsorbing the magnetic conductor 411 so that the inner cover 4 is opened together with the pot cover when the pot cover is opened.

[0045] In the embodiment, when the electromagnetic adsorption assembly 2 is disconnected from the power supply, the inner cover 4 is adsorbed on the inner liner 3 due to the proximity of the magnet member 223 to the magnetic conductor 411, and the force of the magnet member 223 adsorbing the magnetic conductor 411 is sufficient to make the inner cover 4 open together with the pot cover; the elastic member 222 is in different compression states when the electromagnetic adsorption assembly 2 is connected to the power supply and disconnected from the power supply, and when the electromagnetic adsorption assembly 2 is connected to the power supply, the elastic member 222 is pressed by the magnet member 223, and at this time, the compression degree of the elastic member 222 is greater than that when the electromagnetic valve 22 is disconnected from the power supply; the elastic member 222 can also be in a compression state when the electromagnetic valve 22 is connected to the power supply, and in a stretching state when the electromagnetic valve 22 is disconnected from the power supply due to the gravity of the magnet member 223 itself and the attraction force of the magnet member 223 on the magnetic conductor 411; in the open cover state of the cooking utensil, the on-off of the electromagnetic valve 22 cannot be controlled by operating the button, so as to avoid the inner cover 4 from falling in the open cover state of the electric rice cooker; in the closed cover state of the cooking utensil, the coil component 221 is connected to the power supply, the magnet member 223 is away from the magnetic conductor 411, and the inner cover 4 is not adsorbed by the inner liner 3, and remains on the inner pot 5 when the cover is opened.
