[0002] In existing glass electric kettles, the bottom and heating element are usually glued together. This assembly method typically presents several problems in actual production:

[0003] Firstly, the adhesive is expensive, costing about 2 yuan per gram, and each glass electric kettle requires at least 4 grams of adhesive.

[0004] Secondly, the process is relatively complicated and labor costs are high;

[0005] Thirdly, the adhesive has a long curing time and requires a large area, which is not conducive to mass production;

[0006] Fourth, after the adhesive cures, it will create thermal resistance between the bottom of the glass kettle and the heating plate, resulting in slow heat transfer, long boiling time, energy saving, and poor user experience.

[0007] Fifth, adhesives easily release unpleasant odors in high-temperature environments;

[0008] Sixth, after the adhesive cures, it forms a rigid connection with the bottom of the glass pot and the heating plate. Due to the different expansion coefficients of the various components, the glass pot may crack during heating and cooling.

[0009] Furthermore, if the adhesive is removed, the heating plate cannot fit tightly against the bottom of the glass pot, resulting in low heat transfer efficiency. Utility Model Content

[0010] The purpose of this utility model is to provide a glass electric kettle with clamp assembly, which solves the technical problems existing in the background art.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] like Figures 1 to 5 As shown, an embodiment of the glass electric kettle with clamp assembly according to the present invention is provided, including a glass kettle body 1, a heating plate 3 disposed at the bottom of the glass kettle body 1, and a heat-conducting coating 2 disposed at the bottom of the glass kettle body 1 and cooperating with the heating plate 3; it also includes a clamp 5, which clamps the bottom of the glass kettle body and the heating plate tightly, so that the heating plate 3 at the bottom of the glass kettle body is tightly connected as one piece, and the clamp 5 has a pressing member 12 on its side and / or end face, which presses the heating plate 3 tightly against the bottom of the glass kettle body 1, so that the heating plate 3 is tightly attached to the bottom of the glass kettle body 1.

[0036] A sealing sleeve 4 is fitted onto the outer bottom of the glass kettle body 1 and the outer upper end of the heating plate 3. The heating plate 2 is connected to the glass kettle body 1 through the sealing sleeve 4. A clamp 5 is fitted onto the outside of the sealing sleeve 4. A clamping element 12 is provided on the clamp 5, such as... Figure 5 As shown ( Figure 4 and Figure 2 (The clamping element 12 is not visible in the middle). The clamping element 12 is used to fix the heating plate 3 so that the heating plate 3 is tightly attached to the bottom of the glass pot body 1.

[0037] Figure 1 The clamping element 12 is a spring piece welded to the clamp 5: the spring piece is welded to the side wall of the clamp 5 by argon arc welding, and the spring piece presses against the sealing sleeve 4 to fix the heating plate 3, so that the heating plate 3 is tightly fitted to the bottom of the glass pot body 1. Similarly, spring pieces are welded to the side wall of the clamp 5 by argon arc welding, with 3 sets of spring pieces welded on the same circumference, each set of spring pieces spaced 120° apart, and each set of spring pieces consists of 1, 2, or more pieces;

[0038] Another structure of the clamping component 12 is a hole protruding outward from the side wall of the clamp 5: During the drilling process, the hole protrudes outward, pressing the sealing sleeve 4 with this protruding hole wall, thus fixing the heating plate 3 and ensuring a tight fit between the heating plate 3 and the bottom of the glass pot body 1. Three sets of holes are drilled on the same circumference of the side wall of the clamp 5, each set spaced 120° apart, with one, two, or more holes per set. The clamping component 12 on the side of the clamp 5 is located within a groove at the bottom of the glass pot body 1. The clamping component 12 compensates for the assembly tolerances between the heating plate 3 and the bottom of the glass pot body 1, preventing displacement or wobbling between them, ensuring a tight fit and effective heat transfer.

[0039] In another embodiment, in order to protect the bottom of the glass pot body 1, a protective shell 6 is also fitted on the outside of the clamp 5, and the protective shell 6 is fixed to the bottom of the glass pot body 1 by the clamp 5.

[0040] In addition, several support columns 8 are provided on the bottom inner wall of the protective shell 6 to support the clamps 5. The support columns 8 help to suspend the clamps 5 on the protective shell 6, facilitating the flow of gas inside the protective shell 6.

[0041] Specifically, an electric kettle coupler 9 is installed inside the protective shell 6, and the electric kettle coupler 9 is embedded in the inner bottom wall of the protective shell 6 and is electrically connected to the heating plate 3. In use, the electric kettle coupler 9 is used to cooperate with the electric kettle coupler installed on the heating base (not shown in the figure) that matches the glass kettle to supply power to the heating plate 3.

[0042] As one embodiment of clamp 5: see [link] Figure 4 The clamp 5 includes a retaining ring 501. The upper end of the retaining ring 501 is provided with several cards 502, and the lower end is provided with several support feet 503. These cards 502 and the retaining ring 501 are used together to clamp the sealing sleeve 4 to the bottom of the glass pot body 1 and the heating plate 3 to prevent the sealing sleeve 4 from falling off. These support feet 503 are used to support the clamp 5 on several support columns 8, so that there is a certain gap between the clamp 5 and the protective shell 6 to facilitate air circulation.

[0043] More specifically, the above-described clamp 5 embodiment includes six cards 502 and six legs 503, with an angle of 60° between adjacent cards 502 and an angle of 60° between adjacent legs 503. It can be understood that the number of cards 502 and legs 503 is not limited to the six shown in the illustration, but can also be 2, 3, 4, 5, 8...N. Furthermore, it can be understood that, in addition to the structure shown in the illustration, clamp 5 can also employ any other snap-fit ​​structure that achieves the same locking function, such as a snap-fit ​​structure without legs, only with cards.

[0044] Specifically, a vent 10 is provided on one side of the protective shell 6 for releasing the gas inside the protective shell 6. Depending on actual needs, a corresponding one-way vent valve or air plug can also be installed on the vent 10.

[0045] Specifically, a through hole 11 is provided in the center of the bottom of the protective shell 6, and an electric kettle coupler 9 is installed inside the through hole 11.

[0046] Specifically, the thermally conductive coating 2 is a silicon-based thermally conductive coating, composed of silicone resin and ceramic / metal fillers. Its function is to conduct the heat generated by the heating plate 3 to the glass pot body 1.

[0047] The advantages of the clamp-assembled glass electric kettle provided by this utility model are: the glass kettle and the heating plate are fastened together by a snap-fit ​​method, which saves adhesive, and the assembly process is simple, with low labor costs, no thermal resistance, fast heat transfer speed, short boiling time, high economic benefits, and is suitable for mass production.

[0048] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
