Protrusion 4 is provided on wall.One in pot cover and pot body with jacket 1 or inner core 2 it is fixed, another can pass through above-mentioned shaft
Drive inner core 2 and jacket 1 to relatively rotate, inner core 2 and jacket 1 relatively rotate at least partly during, protrusion 4 and elastic slice
The wall surface of 3 relative rotations and raised 4 extrusion elastics 3, elastic slice 3, which is extruded deformation and generates, hinders inner core 2 and the relative rotation of jacket 1
Resistance, and then hinder the relative rotation between pot cover and pot body.The structure of the damping structure is more stable, the service life is longer, energy
Enough to avoid existing cooking apparatus existing bow-backed, take-off problem during uncapping as far as possible, damping and user experience are good, and
Structure is simple, Assembling Production is easy, at low cost, small in size.
Wherein, elastic slice 3 and protrusion 4 preferably but are not limited to be made of plastics or metal material.Elastic slice 3 and protrusion 4
Quantity preferably but be not limited to two respectively, can also be respectively one or more.Elastic slice 3 is preferably arc-shaped, and
It is protruded to the direction far from jacket 1, to simplify structure and convenient for providing biggish elastic force.It is highly preferred that for the ease of adding
Work is provided with opening 13 on jacket 1, and the first end of elastic slice 3 is connected on the side wall of opening 13, second end is vacantly arranged.
Fig. 3 is please referred to, jacket 1 and inner core 2 are both preferably generally cylindrical.For the ease of assembling and using, outside
Clamshell 1 includes the end cap 12 of cover main body 11 and the open end for being set to cover main body 11 open at one end and hollow, in cover main body
11 bottom surface and positioning column 15 is respectively arranged on the inner wall of end cap 12, the both ends of inner core 2 are respectively sleeved at two after installation
On a positioning column 15.It is understood, of course, that ground, is only arranged positioning column on the inner wall of end cap 12 in the bottom surface of cover main body 11 or only
15 also belong to the disposable embodiment of the present embodiment.Understandably, the shape of jacket 1 and inner core 2 is not limited thereto, only
It wants to guarantee that inner core 2 is sheathed in jacket 1 and is relatively rotatable to each other between inner core 2 and jacket 1.
As a kind of specific embodiment, damping structure is installed in the following way: inner core 2 is sheathed on above-mentioned shaft
On, and can be rotated together with shaft, jacket 1 is fixed on pot body.More specifically, referring to Fig. 1 to Fig. 3, jacket 1
Outer wall on be provided with for the fixed mechanism 5 fixed with pot body；Its short transverse is provided with first through hole 21 on inner core 2,
The position that the both ends of jacket 1 correspond to first through hole 21 is respectively arranged with the second through-hole 14, specifically, in the bottom surface of cover main body 11
Positioning column 15 and end cap 12 inner wall positioning column 15 on the second through-hole 14, first through hole 21 and the second through-hole is respectively set
14 for shaft for passing through, relatively unrotatable between inner core 2 and shaft.
Wherein, the structure of fixed mechanism 5 is not specifically limited, and is enabled between jacket 1 and pot body without opposite fortune
Dynamic, for example, fixed mechanism 5 is a protrusion 4, protrusion 4 can be inserted on pot body in corresponding slot.Fig. 4 is please referred to,
First through hole 21 can be arranged in the following way: inner core 2 is hollow tubular structure, is set at the position at middle part in pipe
It is equipped with one piece of plate structure, first through hole 21 is opened up on plate structure, the cross section of first through hole 21 is preferred but is not limited in D
Font or polygon.During pot cover opens or closes, inner core 2 is driven to rotate by shaft, at the same time, protrusion 4 and bullet
Property part relatively rotate and rub, generate the resistance for hindering inner core 2 and jacket 1 to relatively rotate.
Please continue to refer to Fig. 4, (dotted line with the arrow instruction is the rotation side of inner core 2 in pot cover opening procedure in Fig. 4
To), pot cover relative to pot body open at least partly during, the wall surface of raised 4 extrusion elastics 3, and protrusion 4 is outstanding from elastic slice 3
Empty second end is rotated to the first end of elastic slice 3.And preferably, when pot cover is fully opened relative to pot body, protrusion 4 does not reach bullet
The first end of piece 3.
In the present embodiment, pot cover relative to pot body open at least partly during, protrusion 4 from the second end of elastic slice 3 (i.e.
Free end) rotated to the first end (i.e. fixing end) of elastic slice 3, the process early period elastic slice 3 elastic force linear change area it is longer,
The control of 3 elastic force of type selecting and elastic slice of more convenient elastic slice 3；And the process later period, since protrusion 4 does not reach elastic slice 3
The fixing end stress of fixing end, elastic slice 3 is smaller, and deformation is smaller, not easy to break, and the service life can be longer, integrally-built high reliablity.
The working principle of damping structure provided in this embodiment:
When opening pot cover, pot cover drives inner core 2 to rotate by shaft, at the same time, the wall surface of raised 4 extrusion elastics 3,
And protrusion 4 is rotated from the second end of elastic slice 3 to the first end of elastic slice 3, when pot cover is fully opened relative to pot body, protrusion 4 is not arrived
Up to the first end of elastic slice 3.During pot cover is opened, elastic slice 3, which is extruded deformation and generates, hinders inner core 2 and jacket 1 opposite
The resistance of rotation, and elastic slice 3 can generate different resistances by different deformation quantities, and then hinder opposite between pot cover and pot body
Rotation, so that movement of the pot cover in opening procedure is gentler.
It should be noted that elastic slice 3 can also be set to inner core 2 in the present embodiment as disposable embodiment
On, protrusion 4 is set on jacket 1, and the first end of elastic slice 3 is fixed on the outer wall of inner core 2, and second end is vacantly arranged, pot cover
Open at least partly during, the second end of raised 4 readme elastic slices 3 is rotated to the first end of elastic slice 3.Elastic slice 3 is to far from interior
It protrudes in the direction of core 2.As disposable embodiment, inner core 2 is also possible in the present embodiment and is fixed relative to pot body, such as
Installation axle is provided on pot body, inner core 2 is sheathed in installation axle, and relatively unrotatable between inner core 2 and installation axle, pot cover is opened
Or during closure, jacket 1 is directly or indirectly driven to rotate by shaft.In addition, damping structure provided in this embodiment
Application be not limited to cooking apparatus, apply also in the device that other suitably need to buffer, the device include pass through
The first noumenon and the second ontology of shaft and torsional spring rotation connection, the first noumenon and jacket 1 or inner core 2 are fixed, the second ontology
Inner core 2 and jacket 1 can be driven to relatively rotate by shaft, at least partly mistake that the second ontology is opened relative to the first noumenon
Cheng Zhong, the wall surface of raised 4 extrusion elastics 3, and protrusion 4 is rotated from second end to first end.
The technical principle of the invention is described above in combination with a specific embodiment.These descriptions are intended merely to explain of the invention
Principle, and shall not be construed in any way as a limitation of the scope of protection of the invention.Based on the explanation herein, the technology of this field
Personnel can associate with other specific embodiments of the invention without creative labor, these modes are fallen within
Within protection scope of the present invention.
