[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1:

[0026] See Figures 1 to 3 As shown, an all-glass electric kettle includes a kettle body 1 and a heating plate 2 made of a single piece of all-glass, and a heat-conducting plate 3. The heating plate 2 is connected to or close to the lower side of the heat-conducting plate 3. The upper side of the heat-conducting plate 3 is recessed with a cavity. An adhesive material 4 is provided on the outer periphery of the cavity. The heat-conducting plate 3 is adhered to the bottom surface of the kettle body 1 by the adhesive material 4, and a sealed heat-conducting cavity 5 is formed between the cavity and the bottom surface of the kettle body 1. The heat-conducting cavity 5 is filled with a heat-conducting medium 6 that is in contact with the bottom surface of the kettle body 1.

[0027] This electric kettle uses a heat-conducting medium 6 to fill the gap between the heat-conducting plate 3 and the bottom surface of the kettle body 1, ensuring full contact between the heat-conducting medium 6 and the bottom surface of the kettle body 1. This makes the heat conduction more uniform and the heat transfer effect better, facilitating precise temperature control. It also makes the heating or cooling of the glass kettle bottom gentler, avoiding drastic temperature changes and ensuring the safety of using the glass kettle bottom.

[0028] Moreover, the heat-conducting plate 3, through adhesive fixing, speeds up the assembly of the electric kettle, simplifies the structure, improves production efficiency while reducing production costs, and also serves a sealing function.

[0029] The structure is based on the fact that the pot body 1 is made entirely of glass. The pot body 1 is formed by firing the glass as a whole, which is easy to manufacture, has an attractive appearance, makes it easy for users to see the inside of the pot body 1, and is very easy to clean.

[0030] The heat-conducting plate 3 has an adhesive groove 301 recessed around its upper side. The adhesive groove 301 is located on the outer periphery of the plate cavity, and the adhesive material 4 is filled in the adhesive groove 301. The adhesive groove 301 can limit the position of the adhesive material 4.

[0031] The cavity and adhesive groove 301 on the heat-conducting plate 3 are integrally stamped from metal material, making the production of the heat-conducting plate 3 simpler, faster, and cheaper.

[0032] The bottom of the kettle body 1 is also connected to a kettle bottom protective shell 8, and an assembly cavity 9 is formed between the kettle bottom protective shell 8 and the bottom surface of the kettle body 1. The heat conduction plate 3 and the heating plate 2 are set in the assembly cavity 9. The kettle bottom protective shell 8 is mainly made of plastic. The kettle bottom protective shell 8 can hide the heat conduction plate 3 and the heating plate 2, making it safe to use. It can protect the all-glass kettle bottom, prevent the kettle bottom from being bumped, and make it convenient for the kettle body 1 to be placed directly.

[0033] An electric coupler 10 is also provided in the assembly cavity 9. The electric coupler 10 is located on the lower side of the heating plate 2 and is fastened to it. The kettle bottom protective shell 8 is located on the lower side of the electric coupler 10 and is fastened to it. The kettle bottom protective shell 8 has a coupling avoidance hole 801 corresponding to the electric coupler 10. The kettle body 1 can be detached through the electric coupler 10.

[0034] Based on the above structure, when assembling the electric kettle, the heat-conducting plate 3 connected to the heating plate 2 is first attached to the bottom surface of the kettle body 1, then the electric coupler 10 is fastened to the bottom surface of the heating plate, and finally the kettle bottom protective shell 8 is fastened to the electric coupler 10.

[0035] See Figure 4 As shown, the heat-conducting plate 3 is provided with a retaining ring 302 that abuts against or is close to the bottom surface of the kettle body 1. An avoidance channel 303 is formed in the retaining ring 302 that is separated from the heat-conducting cavity 5. A temperature sensing probe 11 is connected to the electrocoupler 10. The temperature sensing probe 11 abuts against the bottom surface of the kettle body 1 through the avoidance channel 303, so that the temperature sensing probe 11 can directly contact the bottom surface of the kettle body 1, making the temperature sensing more accurate.

[0036] The side wall of the kettle body 1 is provided with a handle 12, and the lower part of the handle 12 is connected to the bottom protective shell 8 of the kettle.

[0037] In this embodiment, the adhesive material 4 is glue; the thermally conductive medium 6 is preferably a low-temperature metal material, which includes metallic tin. In other embodiments, thermally conductive silicone grease or thermally conductive oil can also be used instead. Example 2:

[0038] See Figure 5As shown, the bottom surface of the pot body 1 is provided with a ring of protruding ribs 7 in the circumferential direction corresponding to the adhesive groove 301. The protruding ribs 7 penetrate into the adhesive groove 301 and are in contact with the adhesive material 4.

[0039] The cross-sectional shape of the adhesive groove 301 matches that of the protruding rib 7. In this embodiment, the cross-sectional shape is a parallelogram structure that is wider at the top and narrower at the bottom. The protruding rib 7 increases the contact area between the pot body 1 and the adhesive material 4, making the two adhere more firmly and stably. When the protruding rib 7 extends into the adhesive groove 301, some of the adhesive material 4 can be squeezed upwards, so that the adhesive material 4 completely fills the space defined by the groove wall of the adhesive groove 301, the outer bottom wall of the pot body, and the surface of the protruding rib 7. Example 3:

[0040] See Figure 6 As shown, a water inlet pipe 13 is inserted through the handle 12, and one end of the water inlet pipe 13 extends into the assembly cavity 9; the kettle body 1 has a water outlet 101 at the upper part corresponding to the handle 12, and the water outlet 101 is connected to the other end of the water inlet pipe 13; the electric coupler 10 has a water inlet valve core 13 at its center, and the water inlet valve core 13 is connected to one end of the water inlet pipe 13; this structure enables the electric kettle to realize the water filling function of the handle 12. Example 4:

[0041] Example 4 differs from Example 1 in that: Figure 7 and Figure 8 As shown, the heat-conducting plate 3 is omitted. The metal plate 21 in the heating plate 2 has a cavity on its top surface. The cavity abuts against the outer bottom surface of the pot body 1, thereby forming a sealed heat-conducting cavity 5 between the cavity and the outer bottom surface of the pot body 1. In this embodiment, the metal plate 21 is connected to the pot body by a fixing component.

[0042] The fixing component includes a clamp 14. The bottom of the pot body 1 is provided with a neck ring 102 for applying the clamp 14. Both ends of the clamp 14 are provided with fixing ears 141 and fixing holes 142 are provided on the fixing ears 141. The clamp 14 can be fixed to the neck ring 102 by passing a bolt through the fixing holes 142 and tightening it with a nut.

[0043] Furthermore, the clamp 14 is circumferentially connected with several evenly spaced connecting ears 15 by welding or fasteners (screws, rivets, etc.). The connecting ears 15 are formed by continuous bending, and their main body has a C-shaped structure. The bottom wall of the connecting ear 15 is provided with a threaded hole 151. The metal disc 21 is provided with an elongated through hole 211 corresponding to the threaded hole 151. By passing a screw through the elongated through hole 211 and tightening it with the threaded hole 151, the metal disc 21 can be fixed to the bottom surface of the pot body 1. Moreover, the elongated through hole 211 allows for circumferential rotation and fine adjustment of the position during tightening.

[0044] In addition, an elastic support arm 16 can be fastened to the bottom surface of the metal plate 21. The end of the elastic support arm 16 is provided with a U-shaped bayonet 161. The temperature sensor of the electric kettle can be directly attached to the U-shaped bayonet 161 of the elastic support arm 16. The elastic support arm 16 does not need to be installed on the electric coupler 10.
