The tail of one of the coils is connected to a wire. The wire is connected to the conductive sheet on the central bump, and the conductive sheet is connected to the coil to form a circuit loop.

Preferably, the cup holder has three layers, the surface layer is made of glass, the middle layer is made of iron, and the bottom layer is made of plastic.

Preferably, under the action of gravity of the water cup, the cup holder connects the conductive sheet on the bump to the coil to generate alternating magnetic field, and the ferromagnetic material in the middle of the cup holder cuts the lines of magnetic induction to generate eddy current to heat the water cup.

Preferably, the cup holder is divided into two parts, the central small circle part and the outer ring part, and the number of energized coils is automatically selected according to the size of the placed cup to ensure the heating effect.

Preferably, the coil is made of copper.

Preferably, there are eight springs. Eight springs are evenly arranged to ensure the stability of the base.

The beneficial effect of the electromagnetic water cup heater of the present invention is: the electromagnetic cup heater of the present invention presses the cup on the cup holder to connect the conductive sheet to the coil, and at the same time automatically selects the number of coils connected according to the size of the cup to select the heating degree , After the current is turned on, an alternating magnetic field is generated. The ferromagnetic material of the cup holder cuts the magnetic induction line and generates an eddy current, thereby heating the water cup. When the cup is picked up, the circuit is disconnected, the magnetic field disappears, and the heating is stopped. It is convenient to use.

Detailed ways

The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in FIG. 1 and FIG. 2 , an electromagnetic cup heater includes a base 2 , a cup holder 4 , a bump 7 , a coil 1 , and a wire 10 .

There is a mounting groove 6 in the base 2, a spring 3 is arranged at the bottom of the mounting groove 6, and the cup holder 4 is installed on the spring 3 in a suspended state; the cup holder 4 is divided into two parts according to the size of the cup, the central small circle part 12 and the outer ring part 13 The cup holders 4 of the two parts are provided with three projections 7 extending downwards, and the conductive sheets 11 are arranged on the projections 7, and the conductive sheets 11 on the two projections 7 in the center are connected to the wires 10; the bottom of the base 2 places two There are two separate coils 1 bent and wound, the centers of the two coils 1 are facing the center of the installation slot, and the tail of one of the coils 1 is connected to the wire 10. The wire 10 is connected to the conductive sheet 11 on the central bump 7, and the conductive sheet 11 is connected to the coil 1 to form a circuit loop.
