▎ 摘　　要

NOVELTY - The chamber has an inner charging chamber provided in a shell body and connected with an outer shell. A surface of the inner charging chamber is provided with a charging seat for containing a wireless Bluetooth earphone. A surface of the charging seat is provided with a graphene heating sheet and a temperature sensor i.e. thermistor. A microcontroller (MCU) processor is connected with the graphene heating sheet and the temperature sensor. The temperature sensor monitors surface temperature of the wireless Bluetooth earphone. The MCU processor controls the graphene heating sheet to heat a surface of the wireless Bluetooth earphone when surface temperature of the wireless Bluetooth earphone is lower than preset temperature. USE - Pre-heating function featured wireless Bluetooth earphone charging chamber. ADVANTAGE - The chamber heats a surface of the wireless Bluetooth earphone by a graphene heating sheet, avoids strong stimulation of ear canal under cold environment caused by low temperature of the earphone shell, and realizes earphone shell preheating function to improve user experience in cold environment. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a pre-heating function featured wireless Bluetooth earphone charging chamber.
