[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] As Figures 1-5 shown, in the first embodiment: A new type of electric kettle is provided, which includes an electromagnetic heating base 4, an electromagnetic heating component 2 cooperating with the electromagnetic heating base 4, and a container body 1 disposed on the electromagnetic heating base 4. The electromagnetic heating component 2 is externally disposed on the container body 1 and is disposed at the lower part of the container body 1. The electromagnetic heating component 2 and the container body 1 form an integral component. The electromagnetic heating component 2 includes a heat transfer carrier 201 and an electromagnetic induction member 202 that is heated by electromagnetic induction.

[0027] Specifically, the container body 1 can be used to hold liquid. The electromagnetic heating component 2 is installed on the container body 1. The container body 1 is placed on the electromagnetic heating base 4 through the electromagnetic heating component 2. When the electromagnetic heating component 2 is powered on and operates, the electromagnetic induction element 202 generates electromagnetic induction with the electromagnetic heating base 4, and transfers heat through the heat transfer medium 201 to heat the liquid in the container body 1. The heat generated by the electromagnetic induction element 202 is transferred to the heat transfer medium 201. The heat transfer medium 201 increases the heat conduction area, enabling the heat to be transferred more evenly and rapidly to the liquid in the container body 1. The electromagnetic induction element 202 can effectively prevent the electromagnetic heating coating in the prior art from wearing and falling off due to long-term use, and there is no need to worry about the safety hazards caused by direct heat conduction.

[0028] Furthermore, as Figures 2-4 shown, the electromagnetic heating component 2 can be installed at the bottom of the container body 1, or on the side, or surround the bottom of the container body 1; the electromagnetic induction element 202 is made of electromagnetic heating metal material or electromagnetic heating ceramic material.

[0029] Specifically, the electromagnetic heating metal element includes one or more combinations of silver, copper, gold, aluminum, nickel, iron, lead, etc.; or, the electromagnetic heating metal element includes iron-based material, stainless steel material, or aluminum-based material.

[0030] Furthermore, the heat transfer medium 201 is made of thermal grease, or thermal silica gel, or rubber, or plastic or metal powder; the heat transfer medium 201 is a thermal grease layer, or soft glue, or gasket, or backing plate.

[0031] Specifically, the heat transfer medium 201 is made of thermal grease, or thermal silica gel, or rubber or plastic. The material properties of thermal grease, thermal silica gel or rubber or plastic enable the heat transfer medium 201 to have good high-temperature resistance and oxidation resistance, and can maintain a good working state for a long time of use. At the same time, it can also effectively prevent aging and cracking due to long-term use, and thermal grease, thermal silica gel or rubber or plastic has an anti-slip effect, which can prevent the container body 1 from sliding when placed on the electromagnetic heating base 4. When the heat transfer medium 201 is produced, the electromagnetic induction element 202 and the heat transfer medium 201 are integrally formed by a mold, which can be understood by those skilled in the art.

[0032] Furthermore, the heat transfer medium 201 is a soft body, or a hard body, or a viscous liquid, and the container body 1 is made of glass.

[0033] Specifically, when the heat transfer medium 201 is a soft body, the soft body refers to a soft and deformable material, which can fit well with the heat transfer surface during the heat transfer process. The soft body heat transfer medium 201 includes but is not limited to thermal silica gel pads, flexible thermal conductive materials;

[0034] When the heat transfer medium 201 is a rigid body, the rigid body refers to a hard and shape-fixed material with high thermal conductivity. The rigid body heat transfer medium 201 includes, but is not limited to, copper, aluminum, and ceramics;

[0035] When the heat transfer medium 201 is a viscous liquid, the viscous liquid heat transfer medium 201 refers to a liquid with a certain viscosity that provides good heat conduction effects.

[0036] Furthermore, as Figure 3 shown, the electromagnetic induction component 202 is adhesively placed below the heat transfer medium 201.

[0037] Specifically, by adhesively fixing the electromagnetic induction component 202 and the heat transfer medium 201 together, the stable connection between the two during the heating process is ensured, preventing misalignment or separation caused by movement or vibration; the tight adhesive fixation ensures that the heat generated by the electromagnetic induction component 202 can be transferred to the heat transfer medium 201 more efficiently and evenly, improving the overall heat conduction efficiency.

[0038] Furthermore, as Figure 4 shown, a power supply board 7 electrically connected to the coil disc 5 is also provided on the electromagnetic heating base 4.

[0039] Specifically, the combination of the coil disc 5 and the power supply board 7 ensures the stability and continuity of the electromagnetic heating process.

[0040] Furthermore, as Figures 3-5 shown, a support plate 8 for supporting the container body 1 is also provided on the electromagnetic heating base 4. The electromagnetic heating assembly 2 further includes a heat insulation member 203. One end face of the heat insulation member 203 is in contact with the magnetic induction member 202, and the other end face of the heat insulation member 203 is in contact with the support plate 8.

[0041] Specifically, the heat insulation member 203 effectively isolates the magnetic induction member 202 and the coil disc 5, preventing heat from being directly conducted to the electromagnetic heating base 4, thereby reducing the impact of high temperature on the electromagnetic heating base 4 and its internal electronic components and improving the safety of the overall device.

[0042] Furthermore, as Figure 3 and Figure 5 shown, the heat insulation member 203 is silicone, or mica sheet, or heat insulation cotton, or plastic.

[0043] Specifically, the heat insulation member 203 can effectively block the transfer of heat, thereby preventing heat accumulation in the device due to long-term use and improving the working efficiency of heating; secondly, by combining the heat insulation member 203 with the bottom case 3, an effective thermal resistance layer can be formed to prevent direct heat transfer.

[0044] Furthermore, as Figure 3 and Figure 5As shown, the electromagnetic heating component 2 further includes a sealing layer 204. The heat transfer medium 201, the electromagnetic induction element 202, and the heat insulation element 203 are adhesively fixed together through the sealing layer 204. The sealing layer 204 surrounds the periphery of the heat transfer medium 201 and the electromagnetic induction element 202 and is connected to the heat insulation element 203. The sealing layer 204 is at least formed by a soft solid sealing ring or cured liquid silicone.

[0045] Specifically, the sealing layer 204 tightly fixes the heat transfer medium 201, the electromagnetic induction element 202, and the heat insulation element 203 together, preventing heat leakage and movement between components. The sealing layer 204 is formed by a soft solid sealing ring or cured liquid silicone, ensuring good sealing effect and mechanical stability. In this embodiment, the sealing layer 204 is preferably formed by curing liquid silicone.
