[0003] In the structure of the traditional electric kettle, a heating element and an electrical connector are usually provided in the heating base. The heating element is a key component for energy conversion, which converts electrical energy into heat energy. It transmits heat to the water in the kettle by contacting the bottom surface of the kettle. The electrical connector, such as a coupler, is used to connect the external power supply to provide electrical energy for the heating element to work normally.
[0004] The heating element of the traditional electric kettle has a problem of large energy loss in the process of converting electrical energy into heat energy. This is due to the design and material limitations of the heating element, resulting in low heat energy conversion rate. It takes a long time to heat the water in the kettle to the required temperature, affecting the user's experience and efficiency.
[0005] The heat insulation treatment between the heating element and the electrical connector of the traditional electric kettle is often not perfect. This will cause the heat generated by the heating element to be transmitted to the electrical connector, which may cause the electrical connector to age and damage due to high temperature, shortening its service life. On the other hand, the loss of heat also reduces the overall energy utilization efficiency and increases energy consumption.
[0006] The lack of effective heat insulation measures may also affect the normal work of other components around the electric kettle, such as the high temperature of the heating base shell, which may cause burns to the user, and also has an adverse effect on the stability and reliability of the electric kettle as a whole.
[0007] Therefore, it is necessary to propose an improved technical solution to solve the above problems. UTILITY MODEL CONTENT

[0031] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0032] Please refer to Figures 1-4 In the embodiments of the present application, a high-heating-efficiency electric kettle comprises a kettle body 1 and a connected heating base 2, the heating base 2 is internally provided with a heating body 3 acting on the bottom surface of the kettle body 1 and an electrical connector 4 electrically connected to the heating body 3.
[0033] The heating body 3 is arranged in the heating base 2 close to the bottom surface of the kettle body 1, the electrical connector 4 is located in the heating base 2 adjacent to the heating body 3 and on the side away from the bottom surface of the kettle body 1, the heating body 3 and the electrical connector 4 are fixedly connected through a connecting structure, and a heat insulating body 5 is clamped between the heating body 3 and the electrical connector 4 to form a heat insulation barrier through the heat insulating body 5.
[0034] In the technical solution of the present application, a material with excellent heat insulation performance is selected as the heat insulating body 5, such as ceramic fiber, aerogel, etc. The microstructure of these materials determines their low thermal conductivity characteristics. Taking ceramic fiber as an example, it is formed by a large number of fine fibers interlaced with each other, and there are many small pores between the fibers. These pores can effectively hinder the conduction of heat. When heat is transmitted to the heat insulating body 5, the heat needs to be reflected and scattered many times in these pores, thereby greatly prolonging the heat conduction path, making it difficult for heat to quickly pass through the heat insulating body 5, and achieving good heat insulation effect. Aerogel has extremely high porosity and extremely low density, and its nanoscale pore structure can greatly limit the heat conduction and convective heat transfer of gas molecules, so that the heat transfer inside the aerogel becomes extremely slow. By applying these heat insulation materials between the heating body 3 and the electrical connector 4, the heat transfer of the heating body 3 to the electrical connector 4 in the direction of the electrical connector 4 can be effectively prevented.
[0035] The heat insulator 5 is clamped between the heat generating body 3 and the electrical connector 4 and directly located in the heat transfer path, so that the heat conduction from the heat generating body 3 to the electrical connector 4 can be blocked at the source, for example, when the heat generating body 3 works, the generated heat first spreads around, and the heat insulator 5 forms a heat insulation barrier at the key position, so that the heat cannot directly flow to the electrical connector 4; the heat insulator 5 is clamped to ensure good contact with the heat generating body 3 and the electrical connector 4, and the clamping mode can increase the contact tightness of the heat insulator 5 and the adjacent parts, reduce the hot air gap, and further improve the heat insulation effect, and meanwhile, through reasonable design of the clamping structure, the heat insulator 5 can also be prevented from being displaced due to vibration or other external factors during the working process of the electric kettle and always maintain the correct position to play the heat insulation role.
[0036] Further, the heat insulator 5 can form a solid heat barrier between the heat generating body 3 and the electrical connector 4, which is like a wall to limit the heat generated by the heat generating body 3 in a certain area and make it mainly conduct to the bottom surface of the kettle body 1, so that the heat is directionally conducted.
[0037] In summary, the heat insulator 5 effectively blocks the heat conduction from the heat generating body 3 to the electrical connector 4, so that the electrical connector 4 works in a relatively low temperature environment, which greatly reduces the possibility of aging, deformation and damage of the electrical connector 4 due to high temperature, for example, in the traditional electric kettle, the plastic shell of the electrical connector 4 may be deformed and the metal contact may be oxidized due to the influence of the heat of the heat generating body 3 after a long time of use, thereby affecting the stability and reliability of the electrical connection, and in the newly designed electric kettle, the presence of the heat insulator 5 enables the electrical connector 4 to maintain a good working state, prolongs the service life and reduces the frequency of maintenance and replacement, thereby saving the cost for the user;
[0038] By preventing the heat from dissipating in unnecessary directions, the heat insulator 5 improves the energy utilization efficiency, so that the heat generated by the heat generating body 3 can be more concentratedly transferred to the water in the kettle body 1, and the energy waste caused by the heat transfer to the electrical connector 4 and the like is reduced, which enables the electric kettle to more effectively heat the water to the required temperature under the same input of electric energy, shortens the heating time, and reduces the energy consumption, and in the long run, the user can obviously feel the reduction of electricity cost, which meets the requirements of energy saving and environmental protection; the directional heat conduction enables the heat to be more concentratedly transferred to the bottom surface of the kettle body 1, improves the heating uniformity of the bottom of the kettle body 1, which helps the water in the kettle to be more quickly and uniformly heated, and avoids the local overheating or overcooling.
[0039] In the embodiment of the utility model, the electrical connector 4 and the heat insulator 5 are in abutment cooperation, so that the heat insulator 5 is tightly attached to the end surface of the heat generating body 3 away from the bottom surface of the kettle body 1.
[0040] By making the electrical connector 4 and the heat insulator 5 abutment, the relative fixation of the electrical connector 4 in the installation position and its own structural features provide a stable pressure point for the heat insulator 5, when the electrical connector 4 contacts the heat insulator 5, the pressure generated by the electrical connector 4 is uniformly transmitted to the heat insulator 5, so that the heat insulator 5 can be closely attached to the end surface of the heat generating body 3 away from the bottom surface of the kettle body 1, and the abutment mode is similar to a simple mechanical pressing device, through reasonable layout and interaction between components, it is ensured that the heat insulator 5 always maintains good contact with the heat generating body 3 during the working process of the electric kettle, and gaps or displacement will not occur due to factors such as vibration, thermal expansion and contraction, etc.
[0041] In the heat conduction process, any small gap can become a "shortcut" for heat transfer, reducing the heat insulation effect, the abutment of the electrical connector 4 and the heat insulator 5 can eliminate or minimize the air gap and other poor heat conduction media between the heat insulator 5 and the heat generating body 3, when the heat insulator 5 is closely attached to the heat generating body 3, the thermal resistance to be overcome increases during the heat transfer from the heat generating body 3 to the heat insulator 5, because the low thermal conductivity material characteristics of the heat insulator 5 are fully utilized, thereby more effectively preventing heat conduction to the electrical connector 4 direction;
[0042] This design can also affect the distribution of heat flow, when the heat insulator 5 is closely attached to the heat generating body 3, it can guide the heat to be more evenly distributed on the surface of the heat insulator 5, reducing the local concentration of heat, which helps to further improve the overall heat insulation performance of the heat insulator 5, so that more heat generated by the heat generating body 3 is transmitted to the bottom surface of the kettle body 1 according to the design requirements, rather than being randomly lost in other directions, thereby improving the heating efficiency and energy utilization efficiency of the electric kettle.
[0043] In the embodiment of the utility model, the connecting structure includes the connecting column 6 arranged on the heat generating body 3 and the lug 7 arranged on the electrical connector 4, the connecting column 6 has the thread groove 8, and the lug 7 has the connecting hole position 9 matched with the thread groove 8.
[0044] The heat insulator 5 is provided with the gap / hole 10 corresponding to the connecting column 6.
[0045] The connecting column 6 is arranged on the heat generating body 3 and has the thread groove 8, and the lug 7 is arranged on the electrical connector 4 and has the connecting hole position 9 matched with the thread groove 8, this design adopts the thread connection mode, and its principle is to realize the fixed connection between the heat generating body 3 and the electrical connector 4 through the rotation matching of the thread.
[0046] The heat insulation body 5 is provided with a clearance or hole corresponding to the connecting column 6, which is used to enable the heat insulation body 5 to be reasonably installed between the heat generating body 3 and the electric connector 4 without affecting the connecting function of the connecting column 6 and the lug 7, and the connecting column 6 needs to pass through the connecting hole 9 of the heat insulation body 5 and the lug 7 when the heat generating body 3 and the electric connector 4 are connected, and the size and shape of the clearance or hole are designed to be just capable of enabling the connecting column 6 to smoothly pass through, and meanwhile, the heat insulation body 5 can be tightly attached to the heat generating body 3 and the electric connector 4 at other positions to play a heat insulation role and prevent the heat insulation body 5 from being displaced.
[0047] In the embodiment of the utility model, the heat generating body 3 is a thick film heat generating body 3 made of stainless steel material, and the connecting column 6 is arranged along the lower end of the heat generating body 3.
[0048] Stainless steel has good thermal conductivity, and in the heat generating body 3 of the electric kettle, electric energy needs to be rapidly converted into heat and transmitted, and the high thermal conductivity of stainless steel helps the heat to be rapidly and uniformly distributed in the heat generating body 3, thereby improving the heating efficiency.
[0049] The thick film heat generating body 3 is made by adopting a thick film process on a stainless steel substrate, and the thick film process usually includes screen printing, sintering and other steps, the heat generating paste is printed on the stainless steel substrate by screen printing, and then high-temperature sintering is performed to tightly combine the metal oxides and other components in the heat generating paste with the stainless steel substrate to form a firm heat generating layer.
[0050] The stainless steel has high mechanical strength, and the connecting column 6 is arranged along the lower end of the heat generating body 3, which is based on the design concept of structural integration, and such design can make the connecting column 6 and the heat generating body 3 become an integral whole, which can be formed at one time or connected through a simple processing technology in the manufacturing process, thereby improving the production efficiency and the overall strength of the product.
[0051] In the embodiment of the utility model, the heat insulation body 5 is provided with at least one layer, which is one or more of stone wool, ceramic fiber, aerogel or other heat insulation materials.
[0052] The multiple layers of heat insulation body 5 can increase the thermal resistance, thereby more effectively preventing the transmission of heat, and each layer of heat insulation material has a certain heat insulation performance, and when the heat passes through the multiple layers of heat insulation body 5 in turn, reflection, refraction and absorption phenomena occur on each interface, thereby gradually increasing the difficulty of heat transmission.
[0053] In the embodiment of the utility model, the wall body 11 is arranged along the lower end of the heat generating body 3 to form a heat insulation chamber 12 acting on the heat insulation body 5.
[0054] The heat-insulating chamber 12 is formed to create a specific heat-insulating environment, and when the wall body 11 is completely surrounded, the space inside becomes the heat-insulating chamber 12, which is used to accommodate the heat-insulating body 5 and optimize the heat-insulating effect through the unique space structure. In the chamber, the heat transfer path and mode are changed. Specifically, when the heat-generating body 3 generates heat, the wall body 11 can block part of the heat from directly spreading to the outside, so that the heat is accumulated in the chamber to some extent, and the heat-insulating body 5 placed in the chamber can better contact the heat-generating body 3 to fully play its heat-insulating performance, limit the heat in the chamber, and reduce the heat transfer to the electric connector 4 and other parts that do not need to be heated. At the same time, the size and shape of the chamber are reasonably designed according to the size, power and heat-insulating demand of the heat-generating body 3, so as to achieve the best heat-insulating effect and space utilization efficiency.
[0055] In the embodiment of the utility model, the cooperation end surface of the heat-generating body 3 and the bottom surface of the kettle body 1 is a plane, so that the heat-generating body 3 is planar.
[0056] The cooperation end surface of the heat-generating body 3 and the bottom surface of the kettle body 1 is designed as a plane, so as to realize the maximum contact area. When the plane end surface of the heat-generating body 3 is attached to the bottom surface of the kettle body 1, a relatively uniform contact interface is formed between them. When the electric kettle works, the heat generated by the heat-generating body 3 can be more widely transferred to the bottom surface of the kettle body 1 through the plane contact interface, so as to effectively ensure that the temperature distribution of the bottom surface of the kettle body 1 is more uniform, improve the uniformity of water heating in the kettle, and is beneficial to the rapid and uniform heating of water.
[0057] In the embodiment of the utility model, the end surface of the heat-generating body 3 corresponding to the kettle body 1 or the bottom surface of the kettle body 1 is sprayed with graphene material to form a heat radiation layer.
[0058] Graphene has good heat radiation capacity in the infrared wave band. When it absorbs the heat generated by the heat-generating body 3, it can effectively radiate the heat in the form of heat radiation. This heat radiation can form uniform heat distribution in the kettle body 1, so that water can more fully absorb heat. Heat radiation is a way of transferring heat through electromagnetic waves. Graphene can convert heat into infrared radiation of a specific wavelength range, and water has good absorption capacity for infrared radiation, which helps to improve the heating efficiency.
[0059] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
