Description

Technical Field

[0001] This utility model relates to the field of electric kettle technology, and in particular to an all-glass graphene liquid heater. Background Technology

[0002] Electric kettles are common heating appliances that heat water by passing electricity through a metal heating element. In existing electric kettle designs, some manufacturers have replaced traditional metal heating elements with graphene layers and electrode plates to increase heating efficiency.

[0003] For example, Chinese utility model patent with announcement number CN209285036U discloses a glass electric kettle, including a heating base and a glass kettle installed on the heating base. The bottom surface of the glass kettle is coated with a far-infrared electric heating film, and flexible conductive sheets are attached to both ends of the far-infrared electric heating film.

[0004] The problem with existing technology is that the heat radiation generated by graphene during operation may cause physical changes in the glass kettle body, resulting in a decrease in resistance. If graphene is directly energized, there is a risk of leakage in the glass kettle body. In addition, China's 3C certification requires that the liquid in the electric kettle be connected to a ground wire during use. Therefore, such products may also be at risk of failing certification and being used unsafely. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a glass liquid heater that improves heating efficiency and avoids the risk of leakage.

[0006] The technical solution adopted by this utility model to solve the problem is: an all-glass graphene liquid heater, comprising a glass pot body and a base, wherein a heating element is installed inside the base.

[0007] It also includes a graphene layer, which is stacked on the top surface of the heating element and closely attached to the bottom surface of the glass pot. A coupler is provided in the base and is electrically connected to the heating element.

[0008] As a further improvement to the above technical solution, the bottom of the glass pot body is provided with a groove for accommodating the graphene layer, and the top of the heating element is embedded in the groove.

[0009] As a further improvement to the above technical solution, the graphene layer is a solid graphene sheet.

[0010] In other embodiments, the graphene layer is a liquid electrothermal coating, and the graphene layer is coated on the top surface of the heating element.

[0011] In other embodiments, the graphene layer is a liquid electrothermal coating, and the graphene layer is coated on the inner wall of the groove.

[0012] As a further improvement to the above technical solution, a support member is also included, which connects and fixes the heating element to the base.

[0013] As a further improvement to the above technical solution, a gasket is provided at the bottom of the glass pot body, and the gasket is located on the outer periphery of the groove.

[0014] The beneficial effects of this utility model are: heat is transferred to the graphene layer through the heating element, and then the heat is conducted to the glass pot body through the graphene layer, avoiding direct contact with the graphene layer, avoiding the risk of leakage, and facilitating the passing of the national 3C certification.

A coupler 5 is provided inside the base 2, and the coupler 5 is electrically connected to the heating element 3. After the heating element 3 is energized and heats up, it conducts heat to the graphene layer 4. The graphene layer 4 emits far-infrared rays when heated, heating the liquid inside the pot. This structure not only utilizes the graphene layer 4 to improve heating efficiency but also prevents the glass pot body 1 from becoming electrified, ensuring high safety.

[0028] The bottom of the glass kettle body 1 has a groove 11 for accommodating the graphene layer 4, and the top of the heating element 3 is embedded in the groove 11. The graphene layer 4 is a solid graphene sheet. The groove 11 can install and fix the graphene sheet, so that the graphene sheet is embedded in the groove 11 and fits against the glass kettle body 1.

[0029] It also includes a support member 6, which connects and secures the heating element 3 to the base 2. The heating element 3 is then secured.

[0030] A gasket 12 is provided at the bottom of the glass pot body 1, and the gasket 12 is located on the outer periphery of the groove 11. It needs to be placed before the glass pot body 1 is installed. The gasket 12 can prevent the bottom of the glass pot body 1 from being worn or damaged by the graphene sheet / coating, and avoid the glass pot body 1 from being damaged by bumps.
