Vacuum electric kettle

Abstract

A vacuum electric kettle includes a vacuum layer disposed between a liner and an outer shell with a heating disc component disposed inside. A matched electrical connector is disposed between the heating disc component and the base that includes a disc body compounded with a heating body. A seal ring clamping platform is arranged at the edge of the disc body. At least two elastic supporting legs are integrated with the disc body and disposed below the clamping platform. A supporting leg locating ring and a seal ring limiting rib are disposed on the liner with a seal ring between the limiting rib and the clamping platform. The heating disc component and the kettle body are positioned in a matched mode through the elastic supporting legs and the supporting leg locating ring. No welding is required between the heating disc component and the kettle body of the vacuum electric kettle.

Claims

1. A vacuum electric kettle, comprising: a double-layer stainless steel kettle body and a base for placing the kettle body, a vacuum layer disposed between a liner and an outer shell of the kettle body, a heating disc component operatively disposed inside the kettle body, a kettle lid and a handle operatively disposed on the kettle body, and a matched electrical connector disposed between the heating disc component and the base, wherein the heating disc component comprises: a disc body compounded with a heating body, a seal ring clamping platform arranged at the edge of the disc body, at least two elastic supporting legs integrated with the disc body, said at least two elastic supporting legs being disposed below the clamping platform, a supporting leg locating ring and a seal ring limiting rib disposed on the liner, a seal ring disposed between the limiting rib and the clamping platform, and the heating disc component and the kettle body are positioned in a matched mode through the elastic supporting legs and the supporting leg locating ring.

2. The vacuum electric kettle according to claim 1, wherein the disc body is a stainless steel disc, the elastic supporting legs integrated with the disc body are in an extruding-outer shape, and ends of the elastic supporting legs are against the supporting leg locating ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(6) As shown in FIG. 1 to FIG. 5, a vacuum electric kettle of an embodiment includes a double-layer stainless steel kettle body and a base 1 for placing the kettle body, where a vacuum layer 4 is disposed between a liner 2 and an outer shell 3 of the kettle body with a heating disc component being disposed inside the kettle body. A kettle lid 5 and a handle 6 are disposed on the kettle body. A matching electrical connector 7 is disposed between the heating disc component and the base. The heating disc component includes a disc body 8 compounded with a heating body, where a seal ring clamping platform 9 is arranged at the edge of the disc body. At least two elastic supporting legs 10, integrated with the disc body, are disposed below the clamping platform. A supporting leg locating ring 11 and a seal ring limiting rib 12 are disposed on the liner with a seal ring 13 being disposed between the limiting rib and the clamping platform. The heating disc component and the kettle body are positioned in a matched mode through the elastic supporting legs 10 and the supporting leg locating ring 11.

(7) In this embodiment, the disc body 8 is a stainless steel disc, the elastic supporting legs 10 integrated with the disc body are in an extruding-outer shape, and ends of the elastic supporting legs 10 are against to the supporting leg locating ring 11. The elastic supporting legs use the above structure, which can make sealing more reliable. The supporting leg locating ring 11 and the seal ring limiting rib 12 on the liner are directly formed on the liner. The seal ring limiting rib 12 and the clamping platform 9 cooperate to prevent the seal ring from displacement. The outer shell and the liner join up to form the kettle body with joints being located on a top end and at a bottom end of the outer shell and the liner.

(8) In this embodiment, the heating body in the disc body 8 compounded with the heating body may be an electric heating tube 14. Certainly, an electric heating film may also be used.

(9) Because the elastic supporting legs are disposed on the disc body, and the heating disc component and the kettle body are positioned in a matched mode through the elastic supporting legs and the supporting leg locating ring, so that a welding technology does not need to be used between the heating disc component and the kettle body, and there is no risk of destroying the vacuum layer. Even if air leaks on the vacuum layer, the heating disc component can be disassembled and reworked, thereby effectively reducing a rejection rate during the production process. In addition, the vacuum electric kettle of the present invention only needs one kettle body to seal the heating disc component and the kettle body by using the seal ring, so that a structure of the vacuum electric kettle is simple, and manufacturing costs are reduced. Because of a function of elastic force between the elastic supporting legs and the supporting leg locating ring, elastic sealing can be achieved, so that the sealing between the heating disc component and the kettle body is more reliable.

(10) The foregoing embodiment is only an individual case of the present invention. Any replacement made according to the spirit of the present invention should be understood as falling within the protection scope of the present invention.
