A glass heating plate is located on the bottom surface of the glass kettle body, and an electric heating film is located on the lower surface of the glass heating plate. Because glass is a poor conductor, it is difficult to implement a proper grounding device, which can easily lead to leakage. Therefore, it is necessary to strengthen the leakage protection of electric kettles. Utility Model Content

The feature is that a leakage-proof conductive block is provided on the upper surface of the glass heating plate. The leakage-proof conductive block extends into the cavity, and the lower end of the leakage-proof conductive block extends to the lower surface of the glass heating plate. The lower end of the leakage-proof conductive block is electrically connected to the ground wire.
[0006] The lower end of the aforementioned leakage-proof conductive block is electrically connected to the ground wire. Specifically, the lower end of the leakage-proof conductive block is electrically connected to a ground wire terminal, and the lower end of the ground wire terminal is electrically connected to the ground wire connector of the upper coupler through a wire.
[0007] The lower end of the aforementioned grounding terminal is provided with a through hole.

The anti-dry burning and jump-out device is attached to the lower surface of the glass heating plate.
[0009] One of the electrodes of the aforementioned heating film is connected to a neutral wire terminal, which is connected to a neutral wire connector via a wire.

[0012] Compared with the prior art, this utility model has the following advantages:
[0013] 1. The aforementioned leak-proof electric kettle includes a heating base and a glass kettle placed on the heating base. The glass kettle includes a lid, a glass kettle body, and a bottom shell installed below the glass kettle body. A lower coupler is provided on the top of the heating base, and an upper coupler that cooperates with the lower coupler is installed inside the bottom shell of the kettle body.

[0027] The anti-leakage electric kettle is designed so that the anti-leakage conductive block 42 is connected to the ground wire. When the glass heating plate 4 leaks electricity, a current is generated. The current is conducted through the anti-leakage conductive block 42 and the upper and lower couplers to the power switch in the heating base 9. The power switch cuts off the power, effectively ensuring the safety of the anti-leakage electric kettle.

The anti-dry-burning jumper 54 is attached to the lower surface of the glass heating plate 4. The anti-dry-burning jumper 54 detects dry-burning by monitoring the temperature of the glass heating plate 4 over a long period of time.
[0031] One of the electrodes of the aforementioned heating film 41 is connected to a neutral wire terminal 52, which is connected to a neutral wire connector via a wire. The other electrode of the heating film 41 is connected to a live wire terminal 51, which is electrically connected to one end of an anti-dry-burning trip 54 via a wire.

The bracket 32 and the fixing plate 34 can better fix the live wire terminal 51, neutral wire terminal 52, ground wire terminal 53, and anti-dry-burning jump 54, and the structure is simple.
[0033] The bracket 32 described above is also equipped with a heat dissipation aluminum fin 33 on its top. The fixing plate 34 is provided with a fixing through hole 342. Four mounting through holes 341 are distributed around the fixing through hole 342.
