Abstract

The present disclosure discloses a damping device, a cooker and a device having a damping structure, wherein the damping device is arranged between a main body and a cover body, comprising a rotary member ( 2 ) fixed on the cover body; a fixed member ( 11 ) fixed on the main body, the fixed member ( 11 ) being a hollow body having openings at two ends, the rotary member ( 2 ) being nested in the hollow body, one of the rotary member ( 2 ) and an inner side wall of the hollow body being provided with a friction member ( 21 ), the other one being provided with an elastic piece ( 14 ); during the process of opening the cover body, the elastic piece ( 14 ) is slidably fitted with the friction member ( 21 ) and generates varying frictional resistance during sliding. The damping device is less susceptible to outside temperature and humidity and thus is less likely to fail.

First claim

What is claimed is:

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.

2. The damping device according to claim 1 , wherein
a deformation corresponding to the damping friction between the friction member and the elastic piece matches a buffer force corresponding to the damping friction.

3. A cooker, comprising the damping device according to claim 1 .

4. The cooker according to claim 3 , wherein
the at least two limiting ribs have a shape that matches the shape of the supporting member, so that the supporting member can be inserted into the cavity formed by the at least two limiting ribs.

5. The cooker according to claim 4 , wherein the at least two limiting ribs have a size that matches the size of the supporting member, so that the supporting member can be inserted into the cavity formed by the at least two limiting ribs.

6. The cooker of claim 5 , wherein the outer casing provide a stress point by using the first cantilever and the second cantilever of the supporting member to bring the outer casing into contact with the cooking body of the cooker.
