In other embodiments, the liner 20 is provided with a guide groove 50 and the notch of the guide groove 50 faces the face cover. The slider 30 is movable within the guide groove 50 and has an extended position and a retracted position. The slide 30 can drive the caliper structure 40 to move, the caliper structure 40 having an unlocked position and a locked position. At this time, the caliper structure 40 may be located above or below the liner 20, which can similarly reduce the thickness of the cover assembly.

According to another aspect of the present application, there is provided a cooking appliance, including a cover assembly and a pan body, the cover assembly is the cover assembly described above. The caliper structure 40 in the cover assembly is located below the liner 20 and the slider 30 is disposed in the guide groove 50 on the liner 20 so that the thickness of the overall structure of the slide plate 31 and the liner 20 is small. The cooking appliance with the cover assembly also has the advantages.

The cooking appliance further includes a trigger provided on the pot body and engaged with the slider 30. The trigger allows the slide 30 to move, i.e. the slide 30 can be moved from a retracted position to an extended position to effect actuation of the caliper structure.

The cooking utensil further comprises a first swing rod, the middle part of the first swing rod is hinged on the lining 20, the first end of the first swing rod is in butt fit with the sliding piece 30, the triggering piece comprises a second swing rod, the middle part of the second swing rod is hinged on the pot body, the first end of the second swing rod is in driving fit with the second end of the first swing rod, and the second end of the second swing rod is a driving end. The middle part of the first swing rod is hinged on the lining 20, so that the first swing rod can rotate around the hinged position on the lining 20, and meanwhile, the first end of the first swing rod is in butt fit with the sliding piece 30, so that the first swing rod can drive the sliding piece 30 to move. The middle part of the second swing rod is hinged on the pot body, namely the second swing rod can rotate around the hinged position on the pot body. The first end of the second swing rod is in driving fit with the second end of the first swing rod, so that rotation of the second swing rod can be transmitted to the first swing rod, and the first swing rod drives the sliding piece 30 to move. The second end of the second swing rod is a driving end, namely the second end of the second swing rod can drive the second swing rod to rotate around the hinging position on the pot body.

The trigger piece further comprises a torsion spring, and the torsion spring is arranged between the second swing rod and the pot body so that the second swing rod drives the first swing rod to move, and the sliding piece 30 is in an overhanging position. The torsion spring enables kinetic energy of the second swing rod during rotation to be converted into elastic potential energy, namely the second end of the second swing rod can rotate from a position far away from the outer surface of the pot body to a position close to the outer surface of the pot body.

When the second end of the second swing rod rotates close to the pot body, the torsion spring can be compressed, namely the kinetic energy of the second swing rod is converted into elastic potential energy of the torsion spring. The rotation of the second swing link enables the second end of the first swing link to rotate away from the pan body, and the slider 30 is movable from the retracted position to the extended position. When the second end of the second swing rod rotates away from the pot body, the elastic potential energy of the torsion spring is released and converted into kinetic energy of the second swing rod, and then the first end of the second swing rod drives the second end of the first swing rod to rotate away from the outer surface of the pot body, so that the sliding piece 30 finally moves from the moving position to the retracting position. Specifically, the arrangement of the first swing rod and the second swing rod can enable the trigger piece to be driven more labor-saving.

The trigger piece still includes the button, and the button sets up on the pot body, and the button includes body portion and the connecting rod of being connected with the first end of body portion, and the second end of body portion is articulated to be connected with the pot body, is provided with the through-hole on the pot body, and the partial structure of body portion stretches out in the through-hole, and the connecting rod is kept away from the second end butt cooperation of the second pendulum rod of body portion one end. The button enables the second end of the second swing link to rotate away from the outer surface of the pan body. The second end of the body part is hinged with the pot body, so that the body part can rotate around the hinge position of the pot body. The through holes provide channels for the extension of the body portion structure.

Specifically, when the second end of the body part rotates around the hinge position of the pot body, the first end of the connecting rod away from the body part can rotate away from the outer surface of the pot body, and then the second end of the second swing rod is driven to rotate away from the outer surface of the pot body.

The term "plurality" as used in the above description means two or more.
