The groove can be used to determine the two electricity The poles and the two spring conductive strips on the cup holder are accurately touched, and the * is not moved on the cup holder. The two spring conductive sheets on the cup holder are connected to the power cord, the power cord has a power switch, and the power cord is connected to a car igniter plug. .

U.S. Patent No. 6,192,787, filed on November 3, 1997, entitled "Electrically heated beverage appliance", discloses an electrically heated beverage appliance. In the invention, the bottom of the cup is made of conductive or heat conductive material, and the sealing strip is connected with the locking strip and the wall of the cup.

In this patent, the cup wall is made of plastic material, and the bottom of the cup has a metal plate, and the metal plate is sealed with an O-ring between the wall of the cup.
