Embodiment Construction

[0009] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0010] Such as figure 1 As shown, the present invention includes a coaster 1 and a coil 2 fixed on the coaster, and the output terminal of the intermediate frequency power supply 3 is connected to both ends of the coil 2 through a switch K.

[0011] The cup 4 is placed on the coaster 1, and the intermediate frequency alternating current generated by the intermediate frequency power supply 3 is passed into the coil 2 to obtain an alternating magnetic field, an eddy current is induced in the spoon 5 in the cup, and the cup 4 is heated according to the thermal effect of the current liquid.

Abstract

The invention discloses an electromagnetic induction heating vacuum cup coaster. The electromagnetic induction heating vacuum cup coaster comprises a coaster body (1) and a coil (2) fixed on the coaster body and is characterized in that an output end of a medium-frequency power supply (3) is connected to two ends of the coil (2) through a switch K. The electromagnetic induction heating vacuum cup coaster has the advantages as follows: beverage is heated by the aid of a spoon in a cup, the injury accident caused by overhigh temperature of the cup due to heat conduction is avoided, and energy loss caused by low heat conductivity of materials is avoided.

Description

technical field [0001] The invention relates to a daily necessities, in particular to a heating coaster. Background technique [0002] The heating coaster can quickly heat the water in the cup anytime and anywhere, which is convenient for people's life. The existing heating coasters on the market are all based on the principle of heat conduction. The heated coaster transfers heat to the cup and heats the water in the cup at the same time. The disadvantage is that the cup is hot after the coaster is heated, which is easy to hurt the hands. , and different cup materials have different heat conduction effects. For example, double-layer glass spacer cups are not easy to conduct heat conduction, so the heating effect is easily affected by the material of the cup. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the technical problem to be solved by the present invention is to provide an electromagnetic induction heating insulation ...
