Description

Technical Field

[0001] This utility model relates to the field of electric kettles, and in particular to a split-type molded vacuum water boiler. Background Technology

[0002] Electric kettles are mainly used for heating water. They generally consist of a kettle body and a heating element located at the bottom of the kettle body, and their structure is relatively simple.

[0003] However, existing electric kettles have the following shortcomings: 1. They do not have a heat preservation function. Although they heat up quickly, they also cool down quickly. 2. They generally use plastic materials as a protective layer to reduce scalding. Their gloss is not as good as that of an all-metal kettle body, which limits their aesthetic appeal.

[0004] Although there are also methods that use vacuum structures to achieve electric hot water insulation, such as Chinese patent 202023158371.2, their aesthetics and molding are relatively complex. Therefore, the key to the design is to ensure that the water injector is easy to process while achieving the desired insulation and aesthetics.

[0005] For example, Chinese patent 202422555000.X has a connected vacuum chamber between the body and spout of the kettle. In particular, the spout is prone to leakage after being bumped, which in turn affects the heat preservation effect. Utility Model Content

[0006] The main purpose of this utility model is to propose a modular vacuum water boiler, which aims to modularize the various parts of the kettle body and improve the heat preservation effect by welding a vacuum layer, while also preventing scalding.

[0007] To achieve the above objectives, this utility model proposes a split-type molded vacuum water boiler, comprising:

[0008] The inner liner is a cavity with an opening at the top.

[0009] The outer pot body is fitted over the inner liner and extends from the opening of the inner liner to the bottom of the inner liner;

[0010] A sealing plate is provided between the bottom of the outer body and the bottom of the inner liner;

[0011] The inner liner, outer body, and sealing plate form a first vacuum cavity;

[0012] The outer body of the vessel is provided with an inwardly shaped water guide section, and the inner liner is provided with a through hole that matches the water guide section. The water guide section is fixed to the outer periphery of the through hole, and the through hole and the water guide section form a water outlet.

[0013] The inner liner, outer body, sealing plate and water guide section form a first vacuum cavity;

[0014] The spout is located at the water outlet.

[0015] In actual processing, the sealing plate can be welded to the inner liner for sealing, and then the upper and lower ends of the outer body can be sealed to the upper end of the inner liner and the lower end of the sealing cap, respectively.

[0016] When the sealing plate and the outer body are integrated into a single module, the upper and lower ends of the module are welded to the upper and bottom walls of the inner liner, respectively, to achieve a seal.

[0017] Both of these processes are performed within a vacuum chamber, thus achieving a seal during manufacturing.

[0018] There is also the welded seal between the molded water guide section and the inner liner;

[0019] The above steps can be adjusted according to the actual structure to form the first vacuum chamber, thereby achieving the function of heating and heat preservation. Attached Figure Description

[0033] like Figures 1 to 3 As shown, a modular vacuum water boiler includes:

[0034] Inner liner 1, wherein the inner liner 1 is a cavity with an opening at the upper end;

[0035] Outer body 2, the outer body is fitted over the inner liner 1, the outer body 2 extends from the opening of the inner liner 1 to the bottom of the inner liner 1;

[0036] A sealing plate 20 is provided between the bottom of the outer body 2 and the bottom of the inner liner 1;

[0037] The inner liner 1, the outer body 2, and the sealing plate 20 form a first vacuum cavity;

[0038] The outer body 2 is provided with an inwardly shaped water guide part 31, and the inner liner 1 is provided with a through hole 32 that cooperates with the water guide part 31. The water guide part 31 is fixed to the outer periphery of the through hole 32, and the through hole 32 and the water guide part 31 form a water outlet 3.

[0039] The inner liner 1, the outer body 2, the sealing plate 20 and the water guiding part 31 form a first vacuum cavity;

[0040] Spout 4 is located at the outlet 3.

[0041] Specifically, the outer body 2 and the sealing plate 20 are integrally stamped or separately welded for sealing. Whether stamping or welding is used to achieve the sealing of both, it can facilitate sealing and welding with the inner liner 1.

[0042] In this embodiment of the utility model, the opening of the inner liner 1 is provided with a first bent portion 51 extending in the axial direction, and the upper end of the outer body 2 is provided with a second bent portion 52 that cooperates with the first bent portion 51. The second bent portion 52 extends toward the first bent portion 51, thereby increasing the welding area between the inner liner 1 and the outer body 2, and further ensuring the sealing of the first vacuum chamber.

[0043] Specifically, the upper end of the sealing plate 20 is provided with a third bent portion 53 extending towards the axis, providing a larger support area. The material is preferably 304 or 316 food-grade stainless steel, and the thickness can be 0.2-2.5mm, which can be selected according to actual needs.

[0044] The water guiding part 31, the first bending part 51, the second bending part 52 and the third bending part 53 can improve the overall structural strength of the water boiler, while reducing the damage (heat damage) caused by the first vacuum layer reaching the critical pressure.

[0045] In this embodiment of the utility model, the second bending part 52 is an inclined surface, which facilitates the placement of the lid, provides aesthetics, and also provides a larger contact area to reduce heat loss. Water droplets will also flow into the inner liner 1 from the inclined surface.

[0046] Specifically, the spout 4 is a single-layer structure, and the end of the spout 4 extends into the inner peripheral wall of the water guide 31 and is fixed to each other. The spout 4 is mainly used in coffee pots, which have a long neck. Therefore, the structure of inserting it into the water guide 31 and then welding it can improve the structural strength and support.

[0047] In this embodiment of the utility model, the spout 4 is a double-layer conformal structure, including an inner layer 41 and an outer layer 42. The outer ends of the inner layer 41 and the outer layer 42 are welded and fixed. The inner liner of the inner layer 41 and the outer layer 42 are respectively welded and fixed to the outer body 2 to form a second vacuum cavity. In actual design, the inner layer 41 and the outer layer 42 can be welded and fixed, and then the outer body 2 can be welded, or they can be welded to the outer body 2 separately and then welded and fixed.

[0048] Specifically, the outer ends of the inner layer 41 and the outer layer 42 are stacked, thereby increasing the contact area and ensuring the sealing of the weld.

[0049] In this embodiment of the utility model, the inner liner 1 is provided with a water inlet in the middle, and the bottom wall of the inner liner 1 is used to install a heating device.

[0050] Specifically, the outer end of the inner layer 41 is provided with a chamfer 6, which reduces the problem of water spillage and improves the applicability of the structure. In contrast, a single-layer structure requires a predetermined angle to achieve this.

[0051] Of course, the guide section can also be extended from the inner liner.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
