In this embodiment, the guiding portion 412 is provided on the side of the magnetic bracket 41 facing the second engaging member 2, and one end of the second engaging member 2 is provided with a protruding structure 23. The protruding structure 23 is arranged in the guiding portion 412 and is arranged in cooperation with the guiding portion 412. The guiding portion 412 is adapted to move relative to the protruding structure 23.

[0076] By providing the guiding portion 412 and cooperating with the protruding structure 23, the magnetic bracket 41 with the first magnetic member 411 can move along the guiding portion 412 after being subjected to the magnetic force from the driving assembly 6, moving from the first unlocking position to the first locking position, avoiding the second engaging member from being affected by the first control assembly, maintaining the engaging state of the first engaging member 1 and the second engaging member 2, and realizing the locking of the first locking device. In addition, by providing the reset elastic member 42, the magnetic bracket 41 can be reset to the first unlocking position after the driving assembly 6 moves away from the magnetic bracket 41, so that the first control assembly can control the unlocking of the first engaging member 1 and the second engaging member 2.

[0077] In this embodiment, the guiding portion 412 is an inner groove body provided at one end of the magnetic bracket 41. The protruding structures 23 are arranged on both sides of the end of the second engaging member 2 and are fitted in the inner groove body. The reset elastic member 42 is arranged in the middle of the groove body and is fixed to the limiting plate 413 and the limiting portion 24 on the second engaging member 2 respectively. The limiting plate 413 protrudes from one end in the extending direction of the inner groove body.

[0078] As a changeable implementation manner, the guiding portion 412 can also be provided at the end of the second engaging member 2, and the protruding structure 23 is correspondingly provided on the magnetic bracket 41.

[0084] The placement groove 53 includes four lateral openings 531 and a main opening. The lateral openings 531 are also cross-shaped and opened along the side wall of the placement groove 53, extending in the same direction as the child lock elastic member, and are respectively provided with a first connection end 521, a second connection end 522 and a limit end 524, and a limit surface 525 is arranged outside the placement groove 53; the main opening is arranged toward the first locking structure, and a buckle structure 532 is arranged at the end in a barb shape, and the inner diameter gradually decreases along the direction toward the inside of the opening.

[0085] By providing a plurality of lateral openings 531 in the placement groove 53, it is convenient to accommodate the end structures extending in various directions on the adapter 52, and to limit the moving direction of the adapter 52, so as to ensure that the adapter 52 can control the driving assembly 6 to move in the direction toward or away from the receiving assembly. In addition, the stability of the movement of the adapter 52 can be further improved by limiting the upper limit surface 525 of the limiting end 524. The provision of the buckle structure 532 on the main opening further improves the convenience of installing the adapter 52 on the placement groove 53.

[0086] In this embodiment, the driving component 6 is a second magnetic member extending toward the receiving component, and the second magnetic member is arranged in a long strip shape and fixedly connected to the second connecting end 522 along the circumferential side wall. As a convertible embodiment, the second magnetic member can be arranged only at one end of the driving component 6 toward the receiving component.

[0087] In this embodiment, the elastic return member, the button elastic member 32 and the child lock elastic member are all spring members. As a convertible implementation method, one or more of the elastic return member, the button elastic member 32 and the child lock elastic member can also be structures of other elastic materials, such as rubber elastic members or silicone elastic members.

[0088] In addition, the first engaging member 1 includes a first engaging portion 11, and the second engaging member 2 includes a second engaging portion 21 and a rotating shaft 22. The rotating shaft 22 is arranged in the middle of the second engaging member 2. The second engaging portion 21 is arranged at one end of the second engaging member 2 extending toward the first engaging member 1, and is suitable for being engaged and connected with the first engaging portion 11 in a fixed state. A receiving component is provided at the other end of the second engaging member 2. The second engaging member 2 is suitable for rotating along the rotating shaft 22 under the action of the first control component and leaving the fixed state.

[0089] The first engaging portion 11 and the second engaging portion 21 are mutually engaging barb structures. As a convertible embodiment, the first engaging portion 11 and the second engaging portion 21 can also be mutually engaging buckles and slots.

[0090] This embodiment also provides a cooking device, specifically an electric rice cooker, and may also be other cooking devices, such as an electric frying pan, an electric steamer, a steam oven, etc., comprising a cover 7 and a pot body 8 provided with a cooking cavity, and the above-mentioned opening and closing structure, wherein the first piece is the cover 7, the second piece is the pot body 8, the first engaging piece 1 is fixed on the cover 7 in the vertical direction, the first engaging portion 11 is provided at the lower end thereof, and the second engaging piece 2, the first control assembly and the second locking structure are all provided on the pot body 8. As a convertible embodiment, the first piece may be the pot body 8, and the second piece may be correspondingly provided as the cover 7.

[0091] Working process:

[0092] When the cover 7 and the pot 8 are in the closed state, the first engaging member 1 provided on the cover 7 and the second engaging member 2 provided on the pot 8 are engaged with each other via the first engaging portion 11 and the second engaging portion 21 in the shape of hooks, thereby fixing the cover 7 and the pot 8.

[0093] At this time, the driving component 6 on the second control component is located at the second locking position, close to the receiving component, and the driving component 6 is provided with a second magnetic member having the same magnetic properties as the first magnetic member 411, so the receiving component with the first magnetic member 411 will move to the first locking position away from the driving component 6. Since the first locking position is not on the movement track of the abutting end 311 on the first control component, the user presses the cover opening button 31 to control the abutting end 311 to move between the deep position and the pop-up position without affecting the closure of the cover body 7 and the pot body 8, thereby achieving an effective locking state.

[0094] After that, when it is necessary to open the cover body 7 or release the locked state, the child lock button 51 is shifted, thereby controlling the driving component 6 to move from the second locking position to the second unlocking position away from the receiving component. After the magnetic force decreases, the receiving component is reset from the first locking position to the first unlocking position under the action of the reset elastic member 42. At this time, the user can press the opening button 31 to control the abutting end 311 to move from the pop-up position to the deep position, contact and drive the receiving component to undergo a lateral displacement, thereby controlling the second engaging member 2 connected to the receiving component to rotate, and realizing the unlocking of the first engaging member 1 and the second engaging member 2.

[0095] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
