Description

Technical Field

[0001] This utility model relates to a liquid heater, and more particularly to an all-glass liquid heater with high thermal conductivity and uniform heating. Background Technology

[0002] Electric kettles are commonly used liquid heaters, consisting of a glass kettle body and a heating plate. The heating plate is placed against the bottom of the glass kettle body, and the glass kettle body is heated by the heat generated by the heating plate.

[0003] However, existing electric kettles generally increase the heating power of the heating plate or use thermal grease to achieve rapid heating in order to improve heat conduction efficiency and reduce heating time. However, the temperature uniformity on the heating plate is poor, and rapid heating can easily cause the bottom of the glass kettle to crack due to local overheating.

[0004] For example, the patent disclosed in CN218683753U discloses a glass electric kettle in which the upper surface of the heating plate and the bottom surface of the kettle body are coated with thermally conductive silicone grease. The thermally conductive silicone grease is used to increase the heat conduction between the heating plate and the kettle body. However, the temperature of the surface of the heating plate is generally uneven. The rapid longitudinal heat conduction of the thermally conductive silicone grease can easily cause the bottom of the glass kettle body to crack due to local overheating.

[0005] Therefore, there is an urgent need for a liquid heater with high thermal conductivity and uniform heating. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an all-glass liquid heater with high thermal conductivity and uniform heating.

[0007] The technical solution adopted by this utility model to solve the problem is: an all-glass liquid heater with high thermal conductivity and uniform heating, including a glass pot body and a graphene layer. The graphene layer is bonded to the bottom of the glass pot body by thermally conductive silicone grease, and the thermally conductive silicone grease is located between the glass pot body and the graphene layer.

[0008] As a further improvement to the above technical solution, the graphene layer is made of graphene paper.

[0009] As a further improvement to the above technical solution, a heating plate is also included, which abuts against the bottom of the graphene layer, and the graphene layer is not connected to electricity.

[0010] As a further improvement to the above technical solution, a heating base is also included, which is fixedly connected to the bottom of the glass pot body, and the heating plate is mounted on the heating base.

[0011] As a further improvement to the above technical solution, thermally conductive silicone grease is also provided between the heating plate and the graphene layer.

[0012] The beneficial effects of this utility model are as follows: By setting a graphene layer at the bottom of the glass pot body, and bonding the graphene layer to the bottom of the glass pot body with thermally conductive silicone grease, the lateral thermal conductivity of the graphene layer combined with the high thermal conductivity of the thermally conductive silicone grease improves the thermal conductivity while ensuring uniform heating at the bottom of the glass pot body, reducing the risk of the glass pot body cracking due to local overheating.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 3A highly efficient and uniformly heated all-glass liquid heater is disclosed, specifically an electric kettle. It includes a glass kettle body 1, which is entirely glass, and a graphene layer 3. The graphene layer 3 can be, but is not limited to, paper, coatings, or any other form. The graphene layer 3 is bonded to the bottom of the glass kettle body 1 using thermally conductive silicone grease 2. Specifically, the thermally conductive silicone grease 2 and the graphene layer 3 are fixedly connected to the bottom of the glass kettle body 1, with the thermally conductive silicone grease 2 located between the glass kettle body 1 and the graphene layer 3. The heat is first evenly distributed by the lateral thermal conductivity of the graphene layer 3, and then the high thermal conductivity of the thermally conductive silicone grease 2 is used to conduct heat upwards to the bottom of the glass kettle body 1. This improves thermal conductivity while ensuring uniform heating of the bottom of the glass kettle body 1, reducing the risk of cracking due to localized overheating.

[0022] In a preferred embodiment, the graphene layer 3 is made of graphene paper. As a heat-equalizing material, graphene paper has the advantages of high thermal conductivity and lightweight compared with traditional aluminum plates and copper foils.

[0023] In a preferred embodiment, a heating plate 41 is also included. The heating plate 41 abuts against the bottom of the graphene layer 3. The graphene layer 3 is not connected to electricity. Heat is transferred to the graphene layer 3 through the heating plate 41, and then conducted to the glass pot body 1 through the graphene layer 3. This avoids direct contact with the graphene layer 3, avoids the risk of leakage due to the breakage of the glass pot body 1, and improves safety performance.

[0024] In some embodiments, a heating base 4 is also included, which is fixedly connected to the bottom of the glass pot body 1. The heating plate 41 is mounted on the heating base 4, and the heating plate 41 may, but is not limited to, be abutted against the bottom of the graphene layer 3 by a spring.

[0025] In a preferred embodiment, thermally conductive silicone grease 2 is disposed between the heating plate 41 and the graphene layer 3 to improve the thermal conductivity between the heating plate 41 and the graphene layer 3, further improving the thermal conductivity of the liquid heater and reducing the heating time.

[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
