Description

Technical Field

[0001] The utility model relates to the technical field of kettles, in particular to a glass electric kettle. Background Art

[0002] In modern life, electric kettles are a commonly used small household appliance, and their convenience and practicality have attracted much attention. As people's requirements for quality of life improve and they pay more attention to healthy drinking water, glass electric kettles have gradually become a popular product on the market.

[0003] Traditional electric kettles are made of a variety of materials, including stainless steel and plastic. However, stainless steel can become scale-prone over time and is difficult to clean, while also posing a risk of heavy metal precipitation. Plastic, on the other hand, can release harmful substances when heated at high temperatures, posing a potential threat to human health. Glass, on the other hand, offers the advantages of transparency, non-toxicity, odorlessness, and ease of cleaning, allowing users to clearly observe the state of the water inside the kettle, satisfying both health and aesthetic needs.

[0004] In the design and manufacture of glass electric kettles, securing the glass body and heating base is a key technical challenge. Previous connection methods can have drawbacks, such as a loose connection that can cause the glass body to wobble or even fall off during use, compromising safety and stability. Alternatively, complex connection structures can make production and assembly difficult and costly, while also hindering user convenience in daily installation and removal.

[0005] Furthermore, the structural design of the glass kettle's bottom also needed to be optimized. Glass is relatively brittle, so a reasonable structure was needed to enhance its stability and reliability when connected to other components. Furthermore, the connection components needed to be sealed to prevent water from leaking into components like the heating base, potentially creating safety hazards such as electrical shorts.

[0006] Therefore, in order to solve the above problems, developing a novel glass electric kettle connection structure has important practical significance. Utility Model Content

[0014] As a further solution of the present invention: the heating base has a built-in heating element and a coupler electrically connected thereto, and the heating element is in close contact with the bottom surface of the chassis and generates heat in a planar manner.

[0015] As a further solution of the present invention: an annular edge and an annular flange are sequentially formed along the outer periphery of the chassis, and the annular edge and the annular flange are connected in an arc-shaped transition;

[0016] The inner side of the elastic pad is provided with an annular protrusion adapted to the annular edge and an annular supporting groove adapted to the annular flange.

[0017] As a further solution of the present invention: the kettle body and the bottom plate are bent inwardly to form an annular rim, and the annular rim is bent outwardly to form an annular flange.

[0018] As a further solution of the present invention: the inner surface of the elastic pad and / or the outer surface of the elastic pad are provided with anti-slip texture.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1) The cooperation between the elastic pad and the clamping member can provide a strong locking force between the glass kettle body and the heating base, so that the glass kettle body will not shake or even fall off during use, greatly improving the safety and stability of use. The cushioning effect of the elastic pad can effectively reduce the impact on the connection caused by external vibration or improper operation, extending the service life of the connection structure and further ensuring the stability of the connection;

[0021] 2) The raised chassis at the bottom of the glass kettle body enhances the structural strength of the glass kettle itself, reduces the risk of glass breakage due to brittleness, and extends the service life of the glass kettle body.

[0022] 3) Good sealing performance is achieved. The close fit between the elastic pad and the chassis and the compression of the clamp can effectively prevent water from leaking into components such as the heating base, avoiding safety hazards such as circuit short circuits caused by water leakage, and ensuring user safety.

[0023] 4) The heating base is locked with the connecting structure on the hoop to achieve a fixed connection with the glass kettle body.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-7 In an embodiment of the present invention, a glass electric kettle comprises:

[0037] A glass kettle body 1, wherein the bottom end of the glass kettle body 1 extends to form a protruding bottom plate 2;

[0038] The locking assembly 3 includes an elastic pad 4 and a matching clamp 5. The elastic pad 4 is sleeved on the outer periphery of the chassis 2. The clamp 5 is used to apply a locking force to tighten the elastic pad 4 to fit tightly against the chassis 2. The clamp 5 is provided with a connecting structure.

[0039] The heating base 6 is locked with the connecting structure to be fixedly connected to the glass kettle body 1.

[0040] In the technical solution of the present invention, the bottom end of the glass pot body 1 extends to form a protruding chassis 2. This design has multiple functions. First, the protruding chassis 2 provides a stable basic structure for subsequent connection operations. It increases the contact area between the bottom of the glass pot body 1 and other components, making the force distribution more uniform, thereby improving the stability of the connection. Secondly, the convex shape of the chassis 2 can enhance the structural strength of the bottom of the glass pot body 1 to a certain extent, and reduce the risk of glass breaking during connection and use due to its own brittleness; the elastic pad 4 is sleeved on the outer periphery of the chassis 2, and its main function is to achieve a close fit with the chassis 2 through its own elastic deformation. When subjected to external pressure, the elastic pad 4 can adaptively adjust according to the shape and size of the chassis 2 to ensure uniform and close contact with the chassis 2, thereby effectively increasing friction and providing preliminary protection for the stability of the connection. The elastic pad 4 can also play a buffering role, absorbing and dispersing vibrations and impacts that may be generated during use to a certain extent. When the hook 5 is tightened, it will exert uniform pressure on the elastic pad 4, so that the elastic pad 4 can fit more closely on the chassis 2 to form a stable connection as a whole. The design of the hook 5 can be adjusted according to actual needs to adapt to the chassis 2 of glass kettle bodies 1 of different sizes and shapes, and has certain versatility and flexibility. The heating base 6 is fixedly connected to the glass kettle body 1 by locking with the connecting structure on the hook 5. This connection method ensures that the heating base 6 can stably support the glass kettle body 1, and at the same time ensures that heat can be effectively transferred to the water in the glass kettle body 1 to achieve the water heating function. The design of the connection structure needs to take into account the close cooperation with the hook 5 and the convenience of operation, so as to facilitate production assembly and installation and disassembly during daily use by users.

[0041] The support frame 5 is provided with a plurality of support members 12, 13 and 14 and is provided with a plurality of support members 12, 14 and 15. The support members 12 are provided with a plurality of support members 12 and 15. The support members 12 are provided with a plurality of support members 12 and 15. The support members 12 are provided with a plurality of support members 12 and 15.

[0042] In the embodiment of the present invention, the hoop member 5 includes a first hoop body 7 and a second hoop body 8 surrounding the outside of the elastic pad 4. The first hoop body 7 and the second hoop body 8 are respectively provided with a connecting ear 9 and a connecting hole 10 in a locking fit;

[0043] A first connecting post 11 is provided along the lower end of each of the first hoop body 7 and the second hoop body 8 , and a second connecting post 12 connected to the first connecting post 11 with screws is provided in the heating base 6 .

[0044] The hoop member 5 is composed of a first hoop body 7 and a second hoop body 8, which surround the outside of the elastic pad 4. This split design facilitates installation and disassembly operations. During installation, the elastic pad 4 can be first sleeved on the outer periphery of the glass pot body 1 chassis 2, and then the first hoop body 7 and the second hoop body 8 are assembled around the elastic pad 4. The split design is also conducive to flexible adjustment according to different sizes of glass pot bodies 1 chassis 2 and elastic pads 4, thereby improving the versatility of the hoop member 5.

[0045] The first hoop body 7 and the second hoop body 8 are respectively provided with a connecting ear 9 and a connecting hole 10, and the closing of the hoop member 5 is achieved by locking the two together. This connection method is simple and direct. When the connecting ear 9 and the connecting hole 10 are aligned and fixed by appropriate means (such as bolts, buckles, etc.), the first hoop body 7 and the second hoop body 8 can be tightly surrounded by the outside of the elastic pad 4, providing uniform pressure to the elastic pad 4, so that the elastic pad 4 is tightened and closely adhered to the chassis 2;

[0046] A first connecting column 11 (i.e., a connecting structure) is provided at the lower end of the first hoop body 7 and the second hoop body 8, and a corresponding second connecting column 12 is provided in the heating base 6. The first connecting column 11 and the second connecting column 12 are connected by screws. This connection method utilizes the reliability and stability of the screw connection. When the screws are tightened, the first connecting column 11 and the second connecting column 12 are tightly fixed together, thereby achieving a firm connection between the hoop member 5 and the heating base 6. At the same time, the screw connection has a certain degree of adjustability. During the installation process, the accuracy and stability of the connection can be ensured by appropriately adjusting the tightening degree of the screws.

[0047] In summary, the protruding chassis 2 at the bottom of the glass kettle body 1 serves as the basic supporting structure. After the elastic pad 4 is sleeved on the outer periphery of the chassis 2, the elastic pad 4 is tightened and fits tightly against the chassis 2 through the locking cooperation of the first hoop body 7 and the second hoop body 8 of the hoop member 5, thereby enhancing the friction and sealing performance. The first connecting column 11 at the lower end of the hoop member 5 is connected to the second connecting column 12 in the heating base 6 by screws, firmly connecting the glass kettle body 1 and the heating base 6 to form a complete electric kettle structure. The entire connection system, from the bottom of the glass kettle body 1 to the heating base 6, realizes a stable, reliable and easy-to-operate connection function through the coordinated action of various components.

[0048] In the embodiment of the present invention, the heating base 6 has a built-in heating element 13 and a coupler 14 electrically connected thereto. The heating element 13 is in close contact with the bottom surface of the chassis 2 and generates heat in a planar manner.

[0049] The heating element 13 is built into the heating base 6 and is in close contact with the bottom surface of the bottom plate 2. This position design is designed to achieve efficient heat transfer. When the heating element 13 is energized, the heat generated can be directly transferred to the bottom plate 2 of the glass kettle body 1. Due to the close contact between the two, the heat loss during the heat transfer process is small, which can quickly increase the temperature of the water in the kettle and improve the heating efficiency.

[0050] The heating element 13 generates heat in a planar manner. Compared with traditional point or line heating methods, planar heating can provide more uniform heat distribution. This is because planar heating can contact the bottom plate 2 of the glass kettle body 1 over a larger area, so that each part of the bottom plate 2 is heated relatively evenly, thereby avoiding local overheating or overcooling, which is beneficial to uniform heating of water in the kettle and improves the consistency and stability of heating.

[0051] In the embodiment of the present invention, an annular edge 15 and an annular flange 16 are sequentially formed along the outer periphery of the chassis 2, and the annular edge 15 and the annular flange 16 are connected in an arc-shaped transition;

[0052] The inner side of the elastic pad 4 is provided with an annular protrusion 17 adapted to the annular edge 15 and an annular supporting groove 18 adapted to the annular flange 16 .

[0053] An annular rim 15 and an annular flange 16 are sequentially formed along the outer periphery of the chassis 2. This design provides a special structure for the installation and positioning of the elastic pad 4. The annular rim 15 and the annular flange 16 are connected in an arc-shaped transition. The arc-shaped transition is not only smoother in structure and reduces stress concentration, but also enables the elastic pad 4 to better adapt to the shape changes of the chassis 2 when cooperating with the elastic pad 4, thereby improving the fit between the two. The combination of the annular rim 15 and the annular flange 16 forms a structure similar to a groove and a protrusion. This structure can increase the contact area and friction with the elastic pad 4, so that the elastic pad 4 can be more stably fixed on the chassis 2 when subjected to the pressure of the clamp 5, and is not prone to displacement or sliding.

[0054] The inner side of the elastic pad 4 is provided with an annular protrusion 17 adapted to the annular edge 15 and an annular supporting groove 18 adapted to the annular flange 16. When the elastic pad 4 is sleeved on the outer periphery of the chassis 2, the annular protrusion 17 will be embedded in the annular edge 15, and the annular supporting groove 18 will support the annular flange 16. This concave-convex matching design realizes the precise positioning and tight connection between the elastic pad 4 and the chassis 2; when the clamping member 5 applies the locking force, the annular protrusion 17 of the elastic pad 4 will fit tightly in the annular edge 15, and the annular supporting groove 18 will tightly hold the annular flange 16, thereby further enhancing the sealing performance and connection stability between the elastic pad 4 and the chassis 2. At the same time, this matching method can also disperse the pressure applied by the clamping member 5, so that the pressure is more evenly distributed on the chassis 2 and the elastic pad 4, reducing the damage to the components caused by excessive local pressure.

[0055] During the assembly process of the glass electric kettle, the elastic pad 4 is first installed by matching its annular protrusion 17 and annular supporting groove 18 with the annular edge 15 and annular flange 16 of the chassis 2. Then, the first hoop body 7 and the second hoop body 8 of the hoop member 5 are wrapped around the outside of the elastic pad 4 and locked through the connecting ear 9 and the connecting hole 10. At this time, the locking force applied by the hoop member 5 will make the elastic pad 4 more tightly combined with the chassis 2, and the annular protrusion 17 and the annular edge 15, the annular supporting groove 18 and the annular flange 16 will match more firmly. Finally, the second connecting column 12 on the heating base 6 is screwed to the first connecting column 11 on the hoop member 5 to fix the entire structure together. In this process, the special structure of the outer periphery of the chassis 2 and the matching of the elastic pad 4, as well as the connection between the hoop member 5 and the heating base 6, together constitute a stable, reliable and well-sealed connection system, ensuring the normal use and safety of the electric kettle.

[0056] In the embodiment of the present invention, the kettle body and the bottom plate 2 are bent inwardly to form an annular edge 15 , and the annular edge 15 is bent outwardly to form an annular flange 16 .

[0057] The kettle body and the chassis 2 are bent inward to form an annular rim 15. This design first increases the structural strength of the connection between the bottom of the kettle body and the chassis 2. The inward bending method forms a groove-like structure at the connection between the kettle body and the chassis 2. This groove not only serves as a part for subsequent cooperation with the elastic pad 4, but also mechanically increases the bending and torsion resistance of the connection part. When the electric kettle is subjected to external forces, such as tipping or collision, the inward-bent annular rim 15 can disperse part of the force, reducing the direct impact on the connection between the kettle body and the chassis 2, thereby improving the stability of the overall structure. From a process perspective, the inward bending operation is relatively simple and can be easily achieved during the manufacturing process through mold stamping or other molding processes. This design not only ensures structural functions, but also helps to reduce production costs and improve production efficiency.

[0058] On the basis of the annular rim 15, the annular rim 15 is bent outward to form an annular flange 16. The design of the annular flange 16 further enriches the structural level of the outer periphery of the chassis 2. It and the annular rim 15 together constitute a "step"-like structure. This structure can provide better positioning and support when cooperated with the elastic pad 4. When the elastic pad 4 is sleeved on the chassis 2, the annular flange 16 can serve as a blocking and supporting structure to limit the position of the elastic pad 4, so that it can be more stably installed on the outer periphery of the chassis 2; from the principle of mechanics, the outward bending of the annular flange 16 increases the rigidity of the outer periphery of the chassis 2. During the heating process of the electric kettle, the temperature change will cause the kettle body and the chassis 2 to expand and contract. The annular flange 16 can adapt to this dimensional change to a certain extent, and by cooperating with the elastic pad 4, it can relieve the stress caused by thermal expansion and contraction, and prevent structural damage caused by stress concentration.

[0059] In the embodiment of the present invention, the inner surface of the elastic pad 4 and / or the outer surface of the elastic pad 4 are provided with anti-slip textures 19 .

[0060] When the inner surface of the elastic pad 4 is provided with an anti-slip texture 19, its main purpose is to increase the friction with the bottom plate 2 of the glass pot body 1. After the elastic pad 4 is sleeved on the outer periphery of the bottom plate 2, the anti-slip texture 19 on the inner surface will directly contact the surface of the bottom plate 2. These textures can be tiny protrusions, grooves or other irregular shapes. They can be embedded in the tiny gaps or concave-convex parts of the surface of the bottom plate 2 at a microscopic level, thereby forming more contact points and friction. When the clamping member 5 applies a locking force, the anti-slip texture 19 can better prevent the elastic pad 4 from sliding relative to the bottom plate 2, ensuring that the elastic pad 4 fits tightly with the bottom plate 2, thereby improving the stability and reliability of the connection.

[0061] The anti-slip texture 19 on the outer surface of the elastic pad 4 is provided to enhance the friction between it and the clamping part 5. The clamping part 5 surrounds the outside of the elastic pad 4. When the clamping part 5 is tightened, the anti-slip texture 19 on the outer surface will generate greater friction with the inner surface of the clamping part 5. This friction helps the clamping part 5 to grasp the elastic pad 4 more firmly, so that the locking force applied by the clamping part 5 can be more effectively transmitted to the elastic pad 4, thereby prompting the elastic pad 4 to be better tightened and close to the chassis 2. At the same time, the anti-slip texture 19 on the outer surface can also prevent the clamping part 5 from being displaced relative to the elastic pad 4 during use to a certain extent, further ensuring the stability of the entire connection structure.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
