The heat conducting accommodating cavity is easy to contain heat conducting liquid, the silica gel prevents the heat conducting liquid from leaking, and meanwhile, the heat of the heat conducting disc is prevented from being directly conducted to the bottom of the glass kettle.

The heat conducting disc is integrally formed by punching and molding a metal material. The heat conducting plate has good heat conducting performance.

The bottom of the kettle body at the periphery of the bottom of the glass kettle is fixed with a bottom support, and the heat conducting disc and the electric heating device are both arranged in the bottom support. The heat conduction dish and heating device are hidden to the collet, safe in utilization makes things convenient for the kettle body directly to put.

The electric heating device is a heating tube or a heating film or a heating disc, and the electric heating device is fixed on the bottom wall of the heat conducting disc.

And the bottom wall of the bottom support is also provided with an electric coupler mounting hole. The mounting position of the upper coupler is reserved, so that the electric kettle can be conveniently coupled and conducted with the base of the lower band coupler.

The utility model has the advantages as follows:

(1) according to the electric kettle, the kettle bottom is made of glass, scaling is not prone to occurring, the electric heating device indirectly heats the glass kettle bottom through the heat conducting liquid, and the temperature change of the glass kettle bottom is gentle, so that the temperature of the glass kettle bottom is prevented from being changed violently, and the use safety of the glass kettle bottom is ensured.

(2) The kettle body is integrally formed by firing glass, so that the kettle is easy to manufacture, attractive in appearance, convenient for a user to check the conditions in the kettle body and very easy to clean.

(3) The heat conduction liquid is heat conduction oil, and the heat conduction oil heat conduction is even, and heat transfer effect is good, and the accurate temperature control of being convenient for makes the intensification or the cooling of glass kettle bottom relax, and heat conduction dish heat conduction performance is good, and heat conduction appearance chamber holds heat conduction liquid easily, and silica gel prevents that heat conduction liquid from leaking, also avoids heat conduction of heat conduction dish directly to give at the bottom of the glass kettle simultaneously.

(4) The heat conduction dish and heating device are hidden to the collet, and safe in utilization makes things convenient for the kettle body directly to put, reserves upper coupler mounted position, and the electric kettle of being convenient for is electrically conductive with the base coupling of lower band coupler.
