## Abstract

A tooth-brushing cup and heating device consists of a tooth-brushing cup, a hoop, a base and the like an electromagnetic coil, a control circuit and the like are arranged in the base, a display window is arranged at the upper part of the base. Four buttons are arranged above the display window for setting the temperature and the heating time respectively, and a power switch is arranged on the right side of the display window. The hoop is installed on the base, and a conical surface inside the hoop is attached to the outer conical surface of the tooth-brushing cup. The tooth-brushing cup is made of stainless steel by stamping and is in a circular table shape, and a side plane is stamped on the side wall of the tooth-brushing cup to be tightly attached to a base panel.

## Claims

### Claim 1

A tooth-brushing cup and heating device consisting of a tooth-brushing cup, a hoop, screws, an electromagnetic coil, a power line, a base, a temperature decrease button, a temperature increase button, a heating time decrease button, a heating time increase button and a power switch, wherein:
the electromagnetic coil and a control circuit are arranged in the base, a display window is arranged at the upper part of the base, and the display window displays a current temperature value, a set temperature value and a countdown value of heating time;
four buttons are arranged above the display window for setting temperature increase, temperature decrease, heating time increase and heating time decrease respectively, and the power switch is arranged on the right side of the display window;
the temperature decrease button, the temperature increase button, the heating time decrease button and the heating time increase button are arranged above the display window for setting temperature decrease, temperature increase, heating time decrease and heating time increase respectively, and the power switch is arranged on the right side of the display window;
the hoop is installed on the base, and a conical surface in the hoop is attached to the outer conical surface of the tooth-brushing cup;
the tooth-brushing cup is in a circular table shape, a side plane is stamped on the side wall of the tooth-brushing cup, and the side plane is attached to a base panel; and
