1. A damping device, arranged between a cover body and a cooking body, comprising an inner core and an outer casing,
an outer side wall of inner core being provided with a friction member, and the outer casing comprising a fixed member and a supporting member; the inner wall of the fixed member is provided with an elastic piece so that the friction member can be brought into contact with the elastic piece to create damping friction; the supporting member is arranged on an outer periphery of the fixed member and comprises a first cantilever extending in a first direction from an outer peripheral wall of the fixed member and a second cantilever extending in a second direction from the outer peripheral wall of the fixed member; wherein
the fixed member is provided with a cavity having openings at two ends so as to arrange the inner core in the cavity of the fixed member;
the inner core is in a cylindrical form having a cylindrical outer surface and provided with a through-hole along a height direction of the inner core;
the friction member of the inner core is a protrusion protruding from the cylindrical outer surface of the inner core and protrudes outward along a radial direction of the inner core; the protrusion covers a part of the cylindrical outer surface along an axial direction of the inner core, and from a cross-section view perpendicular to the axis direction, the protrusion has an arc-shaped outer surface, and from a position where the protrusion is connected to the cylindrical outer surface to a top of the protrusion, the protrusion has a tapered width;
the elastic piece is an elastic cantilever, and the elastic cantilever protrudes toward the cylindrical outer surface of the inner core; and the elastic piece is in an arc shape and protrudes in a direction away from the outer casing to simplify the structure of the elastic piece;
the cover body is fixed to the cooking body by means of a hinge shaft to which the inner core is fixed; and
the cooking body is also provided with at least two limiting ribs, and the supporting member can be inserted into a cavity formed by the at least two limiting ribs to limit the supporting member.
