[0028] Reference Figure 1 , Figure 2 and Figure 3As shown, a kettle 1000 of an embodiment of the utility model comprises: a kettle body 100 and a heating device 300, wherein the kettle body 100 comprises a kettle body 110 and a black crystal plate 200, wherein the black crystal plate 200 is connected to the bottom of the kettle body 110, and a receiving cavity is defined between the black crystal plate 200 and the kettle body 110; on the one hand, the black crystal plate 200 has good thermal conductivity and high temperature resistance, and can effectively and evenly transfer heat to the kettle body 100 to improve heating efficiency; on the other hand, the black crystal plate 200 has stable characteristics, remains stable during the heating process, is not easily deformed or damaged due to high temperature, and will not precipitate ions to affect the taste of water.

[0029] Reference Figure 1 , Figure 2 As shown, a kettle 1000 of an embodiment of the utility model, the heating device 300 includes an interface 310 and a graphene sheet, the graphene sheet is connected to the side of the black crystal plate 200 away from the kettle body 110, and the interface 310 is connected to the graphene sheet. The graphene sheet is attached to the black crystal plate 200, and by transmitting current to the graphene sheet, the electrical energy is quickly converted into thermal energy by utilizing the electrical conductivity of graphene. The black crystal plate 200 is in contact with the water in the accommodating cavity, and the heat is quickly transferred to the water by conduction. Due to the efficient heat transfer performance, the whole process is very fast, so that the water is quickly heated to the set temperature. The graphene sheet is relatively fragile, and the black crystal plate 200 has better stability than other materials. Taking metal as an example, when the metal is heated unevenly or partially wetted with water, deformation may occur. This deformation may cause the graphene sheet to crack or deform, affecting the service life. The graphene flakes ensure the heating efficiency of the black crystal plate 200, and the stability of the black crystal plate 200 ensures the taste of the water and protects the graphene flakes from damage. The kettle body 110 is made of glass material. Glass does not release harmful substances, so using a glass kettle 1000 can reduce the negative impact on water quality during the heating process. Glass usually has good heat resistance, can withstand high temperature heating, is not easy to break or deform, and if you forget to add water, the glass material supports dry burning for a long time, ensuring the safety and reliability of the kettle 1000.

[0030] Reference Figure 3 As shown, a kettle 1000 of an embodiment of the utility model further includes a bracket 400 and a heat-insulating cotton 410, wherein the heat-insulating cotton 410 is located between the bracket 400 and the graphene sheet. The presence of the heat-insulating cotton 410 can effectively isolate heat conduction and prevent heat energy from being transferred outward. This helps to concentrate heat on the graphene sheet, improves heating efficiency, and makes heating faster and more efficient. The graphene sheet may be affected by thermal expansion and contraction, and the heat-insulating cotton 410 can slow down this process, and the heat-insulating cotton 410 has a certain protective effect on the fragile graphene sheet, which helps to extend the service life of the graphene sheet.

The gap in the heat insulation grille 420 can form an air barrier. Air is a poor heat conductor, so the speed of heat conduction can be slowed down to create an insulating layer in the heat insulation structure to reduce the flow of heat. Reduce the support 400 and other structures and components inside the kettle 1000 from being affected by the heat generated by the graphene sheet.

[0032] Reference Figure 3 As shown, a kettle 1000 of an embodiment of the utility model includes a conductive member 500, the upper end of the conductive member 500 is connected to the graphene sheet, and the lower end is connected to the interface 310, the interface 310 is externally connected to the power supply, and the conductive member 500 passes through the bracket 400 to conduct electrical energy to the graphene sheet. The conductive member 500 passes through the bracket 400 to prevent the interface 310 from directly contacting the graphene sheet. The bracket 400 and the heat insulation cotton 410 are arranged between the interface 310 and the graphene sheet, which have a heat insulation effect, protect the interface 310, and extend the service life of the kettle 1000.

[0033] Reference Figure 3 As shown, a kettle 1000 of an embodiment of the utility model, the kettle 1000 also includes a temperature sensor 600 and a power control device, one end of the temperature sensor 600 is penetrated through the black crystal plate 200, and is located in the accommodating cavity, can directly contact water, and measure the water temperature, and the other end of the temperature sensor 600 is connected to the thermostat 700, the temperature sensor 600 is used to measure the temperature of the water, and provide it to the thermostat 700, the water temperature reaches the set value, the thermostat 700 will automatically cut off the power supply, stop heating, to prevent the water temperature from being too high. When the temperature drops below the setting, the thermostat 700 will restart the heating element to maintain the water temperature within the set range.

[0034] refer to Figure 3 As shown, in some specific embodiments of the present invention, the kettle 1000 further includes a base shell 800, which is disposed below the black crystal plate 200, and contains a heating device 300 therein, and an interface 310 is disposed through the bottom wall of the base shell 800 for an external power source. The base shell 800 protects the heating device 300. The base shell 800 is also provided with a heat insulation layer to reduce the risk of users being burned by accidental touch.

[0035] Reference Figure 3As shown, a kettle 1000 of an embodiment of the utility model further includes a fuse 710, which is connected to the interface 310. When the current exceeds the rated current of the fuse 710, the fuse 710 will melt, cut off the circuit, and prevent the current from passing. This prevents the electrical appliance from being damaged due to excessive current, and reduces fire and other safety risks, thereby protecting the safety of the kettle 1000 and the user.

The temperature sensor 600 is also connected with a fixing part, which is arranged on the lower end surface of the black crystal plate 200, and plays a fixing role on the temperature sensor 600, preventing the temperature sensor 600 from moving or falling off, which helps to improve the sealing of the kettle 1000.
