Referring to fig. 1, in an embodiment embodying the technical intent of the present invention, there is provided an electric kettle 100, including a kettle body 110 and a kettle lid 120 capable of covering the top of the kettle body 110;

referring to fig. 3 to 7, a connecting arm 1211 is disposed on the pot lid 120, the pot lid 120 is rotatably connected to the pot body 110 via the connecting arm 1211, the connecting arm 1211 includes a rotating connection portion 12111, and a first damping protrusion 1212 is formed on an outer circumferential side of the rotating connection portion 12111;

the kettle body is provided with a second damping bulge 1312 facing the interior of the kettle body; in the structure shown in the figures, the second damping protrusion 1312 is formed on a bracket 1310 provided on the kettle body, but in alternative implementations, the second damping protrusion 1312 may alternatively be formed directly on the kettle body, rather than on a connecting structure or an auxiliary structure attached to the kettle body.

During the rotation of the lid 120 relative to the body 110, the first damping projection 1212 and the second damping projection 1312 will form an interference contact to slow the rotation of the lid 120 relative to the body 110.

The positions of the first damping bulges and the second damping bulges are respectively arranged and the positions of the first damping bulges and the second damping bulges form damping contact, so that resistance generated when the first damping bulges and the second damping bulges form damping contact is formed, the formed moment acting on the rotating axis is short, the lateral acting moment of the resistance moment on the rotating shaft can be reduced, and the pot lid is ensured to keep good balance in the rotating process relative to the pot body.

And the first damping bulge protrudes along the direction far away from the rotating axis, so that basically no lateral force or axial force is applied, the waste of damping force is reduced, and the size of the damping structure is favorably reduced.

In addition, the damping contact takes place in the axial of rotating-structure, and the damping contact surface forms in the position that is nearer apart from the axis of rotation, still is favorable to improving the degree of accuracy of location. The closer the position of the damping contact is to the rotation axis, the lower the requirement on the assembly accuracy is, the lower the assembly or manufacturing error can be tolerated, and the yield and the interchangeability of parts can be improved at a certain angle.

In addition, referring to fig. 2, the electric kettle provided in this embodiment further includes an inner container 1110 in the kettle body; the lid 120 comprises an inner lid 1210, a lower lid 1220 covering the lower part of the inner lid 1210, an upper lid 1230 covering the upper part of the inner lid 1210, and an opening and closing lid assembly 1240 disposed in the inner lid 1210, wherein the opening and closing lid assembly 1240 comprises a rod 1241, a spring 1242 and a rod button 1243. The structure can lock or unlock the kettle cover and the kettle body. In addition, the mounting base 130 is further included, and the mounting base 130 includes a bracket 1310, a bracket top cover 1320, a metal side cover 1330 and a pivot. While the above is an important structure of the electric kettle structure disclosed in this embodiment, the foregoing solution is preferably implemented in combination with the structure depicted in fig. 2, and the following embodiments are also basically based on the structural embodiment depicted in fig. 2, and some modifications may be made to the partial structure, and the detailed description will be made when describing each specific embodiment.

As described above, in the present embodiment, the electric kettle further includes a bracket 1310 detachably connected to the kettle body 110 and disposed at the inner side of the top of the kettle body 110, and the second damping protrusion 1312 is formed on the bracket 1310; the connecting arm 1211 is pivotally connected to the kettle body by a bracket 1310.

The support is arranged to be detachable from the kettle body, so that the kettle cover and the support can be assembled in advance when a product is assembled, an installation assembly is formed and then the kettle cover and the support are assembled with the kettle body, and compared with an assembly mode that the kettle cover is directly installed in the kettle body, the assembly is convenient, particularly the installation of a rotating structure is involved, a larger external operation space can be provided, and the kettle is more favorable. Referring to FIG. 5, one way to achieve the detachable connection is to form a stud 1314 on the bracket 1310, then connect the bracket 1310 to the kettle body through a threaded connection structure, and by detaching the threaded connection fitting the stud 1314, the detachable connection of the bracket 1310 to the kettle body can be achieved.

In addition, the support is located the inside of the kettle body to the rotation connection forms on the support, and the size that vertical direction increases when reducing uncapping becomes mutually, and the less storage space of adaptation, for example when the water receiving, the kettle lid of opening can reduce the size of interfering adjacent other article that are located the insulating pot top.

Moreover, the support is arranged inside the kettle body, the outside is invisible, the electric kettle is more attractive, the hidden design of a partial structure is realized, the structure of the kettle body, particularly the shell of the kettle body, is simpler, and the complexity of manufacturing the kettle body is reduced.

As previously described, in mount 130, pivot 1340 is also included; the bracket 1310 and the rotating connection portion 12111 are formed with shaft holes matching with the shaft holes formed by the pivot 1340. In connection with the structure shown in fig. 5, a support arm 1311 may be optionally formed on the bracket, and a shaft hole to be engaged with the pivot 1340 may be formed on the support arm 1311.

The pivot and the shaft hole form a shaft hole matched connection mode, so that the assembly is convenient, and the connecting arm and the bracket can be allowed to adopt materials or structures with higher rigidity. In other embodiments not shown in the drawings, a connecting arm or a bracket structure with certain elasticity can be adopted, and the connection is realized after deformation, that is, a pivot is formed on one of the connecting arm and the bracket, a shaft hole is formed on the other of the connecting arm and the bracket, and the connecting arm and the bracket can pass through the shaft hole to form matching through elastic change and then rebound, so that the number of parts can be reduced.

As shown in fig. 7 to 10, the number of the connecting arms 1211 is two; the bracket 1310 is provided with a space 1315, and the space 1315 has a space capable of accommodating at least part of the connecting arm 1211. Of course, there are embodiments that use one connecting arm or more than two connecting arms.

Certainly, the arrangement of the two connecting arms with the same specification can be regarded as an optimal implementation mode, the balance of resistance moment is favorably exerted, a straight line approximately parallel to the rotation axis is defined by the two contact points definitely, and the moment with a larger difference between the two different action positions cannot be exerted on the rotating connecting structure, so that the axial deflection trend of the pivot is avoided, and the damping structure can be more stably acted on the basis of the stability of the rotating structure.

The space that keeps away the vacancy portion and form the space that holds the linking arm wraps up the partial structure of linking arm, reduces the direct exposure of linking arm, also can play certain limiting displacement.

In addition, as shown in fig. 6 and 8, a torsion spring 1350 is sleeved on the pivot 1340, and the torsion spring 1350 includes two free ends, which are respectively abutted against or connected to the bracket 1310 and the lid 1210.

One free end of torsion spring 1350 is connected to connecting arm 1311, and is located outside or inside connecting arm 1211. As shown in fig. 8, a torsion spring 1350 is disposed in the clearance 1315, and the elastic force provided by the torsion spring 1350 drives the lid to rotate and open automatically, and due to the torsion spring, a damping structure is necessary to buffer the action and impact of the elastic force.

Besides the structure shown in the attached drawings, other driving methods such as a pressure spring and the like can be used for driving the kettle cover to open. Because the moment applied by the torsion spring and the damping force act around the rotation axis, the moment balance is favorably realized. And no space or structure for installing the pressure spring is needed to be arranged in other directions.

Referring to fig. 10 and 11, the second damping protrusion 1312 includes a deformation part 13122 and a stopper part 13121 connected to the deformation part 13122, and the deformation part 13122 has a thickness smaller than that of the stopper part 13121.

The part of shrink thickness forms the deformation more easily, produces the elastic force by the deformation range change and increases damping frictional force gradually in interfering the contact process, lets the process that the speed slows down also gradual change, tends to steadily, further reduces the inertia impact to the kettle body when the pot lid is opened. In addition, in order to facilitate the deformation, an opening 1319 is provided adjacent to the second damper protrusion 1312, and at least one side of the second damper protrusion is opened, so that the elasticity of the deformation portion or the entire second damper protrusion can be improved.

In a preferred implementation, at least a portion of the first damping projection has a circular arc surface coaxial with the axis of rotation.

The circular arc structure of the first damping protrusion enables the position of damping contact to be basically unchanged relative to the rotation axis, so that the damping force change caused by the deformation part is close to linear change, and the stability can be further improved.

In another scheme of realizing the damping contact, the first damping protrusion and/or the second damping protrusion may be made of a flexible material.

Another damping contact is formed by using a flexible material that can contract and deform, and the flexible material deforms flexibly when in contact with the flexible material to provide a damping force.

As shown in fig. 8 and 9, the pivots 1340 are one in number, the pivots 1340 simultaneously pass through the pivoting connection of at least two of the connecting arms 1211, and the support 1310 forms a support platform 1316, the support platform 1316 having a recess that accommodates part of the pivots 1340.

The single pivot that runs through is favorable to improving rotation synchronism, and for two connected positions, two point location can stable definite an axis, and this arrangement is favorable to guaranteeing that the axis of rotation does not take place to deviate from. Correspondingly, in order to avoid flexible deformation of the pivot, a support platform is additionally arranged to support the pivot.

In an implementation not shown in the figures, the number of pivots is optionally at least two, passing through the rotary connection of at least two connecting arms respectively.

At least two pivots are respectively connected with the corresponding connecting arm and the corresponding rotating connecting part, so that the coaxiality requirement of the pivot hole in the support is reduced in the process, and the pivot can be prevented from being flexibly deformed after being used for a long time when the distance between two ends of the pivot is longer.

Referring to fig. 12 and 13, in another embodiment embodying the technical purpose of the present invention, there is provided an electric kettle, including a kettle body 210 having a cavity for containing liquid and a top opening for communicating the outside with the cavity;

The pot lid is when closing with the kettle body, only covers the partial upper portion opening of the kettle body, and whole upper portion opening is not, can reduce the vertical direction size extension that increases when the pot lid is rotatory to be opened, reduces storage space from this. The opening at the upper part of the other part of the kettle body is always covered, and distilled water drops basically cannot flow to the outside, so that the external pollution is effectively reduced.

In another aspect, the above structure can be understood that the cover and the top surface of the mounting seat together form the top surface of the electric kettle, the top surface with the mounting seat provides part of the top surface of the electric kettle, and the mounting seat providing the rotary connecting structure is skillfully utilized to cover part of the upper opening of the kettle body.
