[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] like Figures 1 to 6 As shown, this utility model claims protection for an electric kettle, including a kettle body 1 and a base 2. The kettle body 1 is provided with a heating plate 3 for heating the water in the kettle body 1.

[0025] A rotary current-conducting structure is provided between the kettle body 1 and the base 2, and the rotary current-conducting structure is electrically connected to the heating plate 3. Specifically, in this embodiment, the rotary current-conducting structure includes an upper coupler 7 located at the bottom of the kettle body 1 and a lower coupler 8 on the base 2. The upper coupler 7 is electrically connected to the heating plate 3, and the lower coupler 8 is connected to an external power source. The upper coupler 7 and the lower coupler 8 are positioned correspondingly and matched for use, and the two achieve electrical connection through rotational contact. As can be seen from the working principle of the coupler, the concentric conductive ring inside the coupler completes the circuit closure, directly transmitting the 220V AC power from the external power source to the heating plate 3 for heating.

[0026] The heating plate 3 is equipped with a temperature sensing structure, which is a temperature sensor, such as an NTC probe, used to monitor the water temperature inside the kettle in real time. When the water temperature reaches a preset threshold, it immediately triggers a power-off mechanism to stop heating, thus preventing dry burning. The temperature sensing structure and its function are existing technologies and will not be elaborated here.

[0027] A handle 9 is provided on the kettle body 1, which makes it easy to lift the kettle body 1 to fill with water or clean it.

The water supply pipe 6 is connected to the water outlet 5 on the side wall of the kettle body 1, and the height of the water outlet 5 is lower than the lowest point of the recessed area 303. The heating plate 3 and the inner wall of the kettle body 1 enclose a water-containing chamber, and the height H1 of the bottom inner wall of the kettle body 1 and the height H2 of the recessed area 303 satisfy the geometric constraint that H1>H2, so that the liquid medium in the water-containing chamber is directed to the water outlet 5 for discharge through gravity.

[0029] In this embodiment, the water supply pipe 6 is a silicone tube, which has the advantages of excellent temperature resistance and good stability. One end of the silicone tube is inserted into the connecting tube 302 for fixation, and the other end extends to connect with the water outlet 5, thereby helping to discharge the water in the kettle 1 through the drain hole 301, the water supply pipe 6, and the water outlet 5, so as to reduce the water residue in the kettle 1.

[0030] The present invention relates to an electric kettle, the core improvement of which lies in reducing water residue inside the kettle body 1 by optimizing the fluid dynamics structure. A drain hole 301 is provided on the heating plate 3, and the drain hole 301 is connected to the water supply pipe 6 through the connecting tube 302. The water supply pipe 6 is connected to the water outlet 5, and the water outlet of the water outlet 5 is lower than the drain hole 301 to achieve gravity drainage, thereby achieving the purpose of reducing water residue inside the kettle body 1.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
